Weapons Of The Special Forces

Special operations. The name says it all: specially trained individuals conducting highly specialized missions using a range of specialized hardware. Whether they are leading cavalry charges of freedom fighters or helping to yank foreign despots from their underground hiding places, U.S. special operations forces have at their disposal the most cutting-edge weaponry.


Looking toward the future, special operations planners are calling for a new-generation weapons system designated the Special Operations Forces (SOF) Combat Assault Rifle (SCAR). Envisioned as a family of weapons, SCAR will be developed in two primary configurations: SCAR-Light (SCAR-L, 5.56 x 45mm) and SCAR-Heavy (SCAR-H, 7.62 x 51mm), with SCAR-L leading the acquisition process. A characteristic of the follow-on SCAR-H model is the use of an Open Architecture design that will accommodate changing calibers from the standard NATO 7.62 x 51mm. The initial caliber change is projected as the 7.62 x 39mm used in the AK-47 and other international weapons series.

Barrett M82 The .50-cal. M82 series long-range sniper rifles entered service during Operation Desert Storm and have proved effective against material targets.

Both SCAR configurations will possess the capability for barrel modularity and thus will be available in the following variants: Standard, Close Quarters Combat and Sniper Variant. Maximum size for the SCAR-L is 29.9 in. (stock collapsed or folded)/33.6 in. (stock extended with standard barrel) with a maximum unloaded weight of 7.25 pounds. Size and weight goals for SCAR-H are 30.3 in. folded/40.2 in. extended with standard barrel, and no more than 9 pounds. Among its capabilities, the SCAR family will be compatible with all components of the SOPMOD kit.

Industry designers have recently unveiled several new weapon design concepts in response to the SCAR requirements. Knight’s Armament, for example, has traced a growth path from its current SR-25/Mk11 weapons to the SCAR-H design. The company has shown great flexibility in recent years, even producing prototypes for an SR-47 (Stoner Rifle) design that was externally identical to the M4 carbine but re-engineered to fire the AK-47 banana clip and 7.62 x 39mm ammo.

“We’ve showed special operations representatives the Mk11 and then we showed them a Mk11 of a different lower receiver that had a collapsible buttstock,” explains David Lutz, Vice President of Military Marketing for Knight’s. “Then we took the upper receiver—which has a 20-in. barrel—off the new collapsible lower receiver and we pulled out what we call ‘The Battle Rifle,’ with either a 16-in. or 14.5-in. barrel. That now goes on the collapsible stock SR-25 lower receiver. As far as we’re concerned, we think this is certainly your ‘immediate term’ SCAR-Heavy.”

Meanwhile, special operations planners continue to support the immediate needs of special operations personnel in the field. For their part, the special operators are continuing to go wherever they are needed and do whatever needs to be done.


Searching for downrange targets, I slid my index finger forward in the trigger guard, hitting the bolt catch release and chambering the first 5.56mm round. The ambidextrous thumb lever on both sides of the handgrip smoothed my lefthanded transition from safe, through semi, to full-automatic fire. The initial burst was directed at a torso target, and the weapon’s high sightline and innovative stock design provided heads-up assurance that the bulk of the bullets were plastering the cardboard victim.

PM was in the Nevada desert to test fire the newest addition to the Army’s small-arms arsenal, the XM8 lightweight carbine system.

“The XM8 is an experimental M8 carbine,” explained Jim Schatz, Manager, Military Programs, HK Defense. “XM8 is the Army designation for what the Army expects will be its new combat assault rifle system. If it is successful and if it’s fielded, the XM8 weapons system is intended to replace the M16/M4 family of weapons.”

Explaining the Army’s need for the new XM8 system, Schatz acknowledged that “the M16/M4 family of weapons have been around for 40 years and they continue to serve the military very well. We take nothing from the design of Gene Stoner. It’s brilliant. But there are certain requirements that the conventional Army has for a new assault rifle to reduce the training burden, to increase the service life, and to increase the reliability of that M16/M4 system.”

The XM8 employs a proven operating system that uses a pusher rod located above the barrel, pushed to the rear by a piston. When a round is fired, gas comes up into the cylinder, pushing a piston rod that strikes the bolt carrier and drives it to the rear.

“Once the piston comes about 6mm to the rear, all the excess gas, which you don’t need to operate the gun, goes out the front, out of the muzzle and out of the gas venthole. And all the carbon goes out of the muzzle with it,” Schatz said.

The operating system is one feature in a totally modular weapons design that Schatz likens to “a Lego set” in terms of its ease of assembling components and accessories.

The XM8 weapons system includes four major variants: Baseline Carbine, Compact Carbine, Sharpshooter and Automatic Rifleman. Automatic firing rates for all variants fall within 700 to 825 rounds per minute. Barrel lengths vary from 9 to 20 in. Firing the standard NATO M855 5.56mm bullet, muzzle velocities vary from 2400 fps (9-in. barrel) to 2700 fps (12.5-in. barrel) to 3000 fps (20-in. barrel).

Moving to the range, our own firing experience with multiple XM8 variant prototypes provided a new appreciation for the design features and inherent program lethality.

As these pages WENT to press, XM8 prototype testing continued through summer 2004 with the formal “decision to adopt” scheduled for September. A positive decision would lead to initial production early in 2005 with the first fielding later that year.

How Entrepreneurs are Building Successful and More Efficient Companies

Every good entrepreneur knows it’s true: besides having a brilliant business idea, employees are any firm’s most valuable asset. But once a business takes off, the romantic idea of founding a successful business in the proverbial garage quickly fades and reality settles in. Fact is, day-to-day issues of HR management can distract you from another key to success: growing your business.

Saving Hours by Outsourcing
The average small business owner spends more than 25 percent of his or her day handling employee-related paperwork. With additional tasks added for recruitment, hiring and training of new employees, this number quickly grows to 35 to 45 percent. In other words, rather than innovating and expanding the business, they spend almost half of any workday on administrative tasks that are a necessary evil.

While 401(k) plans or a premium benefits package keep current employees happy and attract high-caliber candidates, most entrepreneurs prefer to focus on their passion for the business, rather than on HR. They have very limited interest in federal and state regulations regarding everything from workers’ compensation to workplace health and safety, not to mention additional complexities related to employee benefits with the recent passage of the Affordable Care Act. HR outsourcing firms like TriNet, provide small, growing companies a proven way to scale, protect and streamline their business. What’s more — this approach allows entrepreneurs to focus on what matters most to them.

Power and Efficiency Through Integrated Technology Solution
Employees have come to expect anytime access to their HR information. But the cost of implementing and maintaining a state-of-the-art HR information system (HRIS) is simply out of reach for the average small and medium firm. But that’s precisely what TriNet has done — creating an affordable, cloud-based solution and mobile app to enable employees, managers and executives to access the information they need, when they need it.

Risk Mitigation: Share the Liability, Focus on Your Business
In this litigious climate, there is little room for administrative error. HR companies, like TriNet, stay on top of all employment laws and regulations so they can help their clients remain compliant.

With TriNet as your partner, you’ll have the expertise, capabilities and scalable infrastructure to grow. Our core HR services and cloud-based technology streamline the HR process for managers and employees alike.

The Disrupters 2013: The Entrepreneurs Who Are Changing Their Industries

Disruption isn’t cool. Historically, disruptive ideas and companies haven’t been those behind the groundbreaking technologies or products–i.e., the cool stuff. Disrupters aren’t usually first to market with a new invention. They are, however, visionaries who grasp how an existing idea can be made better or cheaper or accessible to millions.

History is littered with examples: Ford’s assembly line and stripped-down Model T brought cars to the everyman. Steve Jobs took the computer mouse, at the time a custom-built and expensive gadget, and had someone figure out how to make it for less than a quarter of the cost. didn’t create online shopping, but it did bring millions of products to one storefront and deliver a better price.

The same goes for our disrupters here. They saw opportunities, ignored by existing players in their fields, to get in, grow big, change the game–and get rich along the way.

HSPA+ vs LTE: Which one is better?

We have all marveled at the revolution in mobile communications technology. The 1980′s saw the introduction of the “brick” style wireless mobile phone accessible to a privileged few. Since then, we have seen a lot of shifting trends in designs and capabilities, but an exponential increase in availability and popularity. We now live in a world boasting over 6 billion mobile phone users, with most high-end devices mimicking the capabilities of a computer, featuring dual-core or even quad-core processing capability.

Ah, the Zach Morris brick.

I still recall a time when the primary purpose of a mobile phone was voice communication. Now, with smartphones bursting onto the scene in ever growing numbers, the mobile landscape is changing rapidly. With devices now featuring messaging, social networking connectivity, email and browsing capabilities, and the ability to stream or download high-quality music and videos, making and receiving calls has almost become a secondary feature.

Of course, none of this would be possible without an equally impressive evolution in mobile networking technology. From first generation communication networks to the current 4G craze, these advances have made it incredibly easy for any user to always be connected. Today we will compare the latest networking technologies, namely HSPA+ and LTE, and take a look at what the future holds.

First generation mobile networks were basic analog systems designed purely for voice calls. Mobile devices and call rates were very expensive and therefore not available to everybody. The early nineties saw the introduction of the first digital cellular networks. 2G brought with it improved sound quality and a higher capacity, allowing for data services, albeit at very low speeds up to 14.4 kbps. Further advances in this technology introduced GPRS and EDGE features with quicker data speeds between 40kpbs to 100kbps.

This was followed by the 3G revolution. Apart from wide-area voice telephony, it introduced high-speed internet access, far improved audio and video streaming capabilities, support for video calls and conferences, and internet TV. With effective speeds ranging from 128kbps to 384kbps, the advent of 3G completely changed the way people use their mobile phones.

The effective entry of the tablet and increasing dependency on handheld mobile devices led to demand for even faster speeds and connectivity options, leading to a new standard, HSPA+, followed by 4G LTE.

What is HSPA+ and LTE?


HSPA+ or Evolved High Speed Packet Access, is a souped-up version of HSUPA and HSDPA 3G standards with speeds comparable to the newer LTE networks. Theoretical speeds are said to feature download speeds up to 168Mbps and uplink of 22Mbps. These are of course theoretical speeds, with the actual speed available to users being much lower. While most HSPA+ networks around the world boast a theoretical 21Mbps(download) speed, T-Mobile(USA) and Deutsche Telekom(Germany) feature 42Mbps networks. A hotly debated issue is the 4G tag offered by cellular network companies to advertise their HSPA+ networks(T-mobile and AT&T), while most accept that it should be considered, at most, a 3.75G network.


On the other hand, LTE, or Long Term Evolution, is considered a “true” 4G network. Theoretical speeds boast downlink speeds of 300Mbps and uploads of 75Mbps. LTE, which is an IP-based system, is a complete redesign and simplication of 3G network architecture resulting in a marked reduction in transfer latency. Because of this, LTE is not compatible with 2G and 3G networks and thus, functions on an entirely different wireless spectrum. Unfortunately, this means that erecting an LTE network requires it to be built from the ground up. This is one of the main factors behind the delayed launch of  complete 4G LTE networks.

Bottom Line

HSPA+ is the tip of the mountain with 3G technology, and LTE is simply the foundation for a new mountain. LTE, also known as 4G, is the most advanced telecommunications technology currently available, and is one that defines a clear path toward future developments, making it the most attractive choice for carriers these days.

Speed Comparison

Neil Shah

The biggest question consumers have is whether the additional cost of buying an LTE-enabled device and the higher data charges are worth it, compared to the “slower” but relatively cheaper 3G and HSPA+ networks. Let’s take a look.

Under consideration are speed comparisons based on the recently conducted wireless speed tests byPCWorld, of the major network carriers in the US (AT&T, T-Mobile, Verizon, and Sprint). For our purposes, we are going to compare the LTE-based AT&T and Verizon 4G networks, against the 42 Mbps HSPA+ based T-Mobile “4G” network. While Sprint and T-Mobile both aim towards launching their LTE networks soon, as of now, they are based on Wi-Max technology and HSPA+ respectively.

PCWorld, along with their testing partners Novarum, conducted the tests using Ookla’s speed test app in 13 cities across the US including San Francisco, Los Angeles, San Jose, Seattle, Las Vegas, Denver, Dallas, Chicago, New Orleans, New York, Washington D.C., and Boston.

There are a few key points to note from the chart above:

  • T-Mobile’s HSPA+42 network performs admirably against, what is supposed to be, far superior LTE networks. The high speeds offered by this network should be more than enough for most users.
  • LTE is fast! While HSPA+ is definitely good enough, the LTE networks(in their current state) are 20-30% faster. A big plus for all the speed demons out there.
  • Unrelated to the topic, but is anyone as surprised as I am at how poorly Sprint’s Wi-Max network performed?

Granted these results for HSPA+ aren’t standard the world over, with most networks featuring 21Mbps download capabilities. But all these network carriers are planning to upgrade to 42Mbps and even 84 Mbps networks, so HSPA+ still has a lot of potential, and is certainly “good enough” for now.

As you can see from the map above, 4G LTE is certainly the network of the future. With the much faster speeds, higher efficiency, and increased reliability, it is the next logical step in network technology development. There are some key points to note about the map though, which shows that LTE coverage isn’t as “colorful” as it seems:

  • While a lot of countries are marked “red” indicating countries with commercial LTE services, it is slightly misleading. For example, while India as a whole is marked, only one carrier(Airtel) offers 4G LTE services in only one city(Kolkata) thus far. Of course, plans are in the works to rollout the network eventually, it will take quite a lot of time before complete coverage is achieved.
  • The above point is true for most countries, with none boasting a full coverage LTE network. Full coverage in some regions will be achieved at the earliest by late-2013 to early-2014, with most others much later.

On the other hand, HSPA+ is more along the lines of a software enhancement that elevates 3G data network performance. Of course, the process isn’t as simple as it sounds, but it is definitely easier than building a completely new LTE supported network. As such, any carrier that has an established 3G network, have upgraded to an HSPA+ network. With over 100 network carriers worldwide featuring HSPA+ networks with most boasting over 80% coverage. To keep up with current LTE speeds, carrier networks are also upgrading the their “slower” 21Mbps networks to 42Mbps or even 84Mbps (theoretical) download speeds.


As mentioned earlier, the biggest issue with taking advantage of the faster speeds of a 4G LTE network is coverage. Availability is still quite limited but that will of course, get better. What surprised me is the lack of a difference in cost between a carrier’s HSPA+ and LTE networks.

  • AT&T and Verizon have standard data rates of $50 for 5GB regardless of whether you have access to 3G, HSPA+, or 4G LTE networks.
  •  T-Mobile, which currently features a 42Mbps HSPA+ networks, also features the same data rates.
  • In India, while available only in Kolkata so far, 4G LTE costs Rs 1399(~$28) for 9GB, with HSPA+ being Rs 1250(~$25) for 10GB.

Of course, I’ve only used the information from two places I’m most familiar with, so there might be other networks worldwide where there is a more evident price difference (or not), so if there are, do let us know in the comments section.

Device availability

HSPA+ and LTE variations of the Samsung Galaxy Nexus

Device availability is another area where I consider LTE to be at a disadvantage. Here’s why:

  • Most smartphones and tablets (3G versions) released in the last 2 years or so can access the faster speeds offered by HSPA+ networks.
  • On the other hand, accessing a LTE network requires a significant hardware change, i.e. the need for an LTE radio.
  • Options for LTE capable devices are comparatively limited and generally range towards the higher end of the price spectrum.
  • There has been an incompatibility issue with latest Nvidia quad-core Tegra 3 processor and LTE radios, as seen with the HTC One X where the international version features the quad-core processor, and the US releases with LTE radios “falling back” on Qualcomm dual-core Snapdragon S4 processors. Whether this issue will be prevalent in other quad-core processors such as the Samsung Exynos 4412, is yet to be seen.
  • LTE radios are also infamous for being a huge drain on battery life.

The Future


Evolution of HSPA

HSPA+, with its theoretical 168Mbps downlink speeds, still wasn’t the pinnacle of HSPA technology. Back in 2010 began talk of LTHE or Long Term HSPA Evolution. LTHE brought with a lot of advantages including:

  • Backward compatibility with existing WCDMA and HSPA networks. This provided the possibility of an easy transition to LTHE as opposed to a network upgrade to LTE.
  • Theoretical download speeds up to a whopping 672 Mbps.
  • Carriers and hardware companies claimed that LTHE could have been ready for deployment by 2013.

Unfortunately, almost every network around the world has decided to move onto LTE as their network for the future. HSPA+ networks will likely be upgraded to the 42Mbps or even 84Mbps download capability, but now, it seems like that is as far as this evolutionary technology will be pushed.

While HSPA+ was the peak of 3G technology, the current variation of 4G LTE is only the first step in this next stage, opening up numerous possibilities for much further advancement in this field. It is somewhat strange that advances in LTE technology are already being spoken about when the “original” standard networks aren’t even close to being fully established. Yet, that is the rapid speed in which the tech world progresses. Let’s take a look at some of these developments:

  •  TD-LTE:  TD-LTE or Time-Division LTE was developed by China Mobile over the last few years. Unlike LTE networks which carries two separate signals for data traveling in either direction, TD-LTE features a single channel and allocated upload and download bandwidth depending on your usage. This accounts for higher data speeds. TD-LTE is also compatible 4G WiMax and it will easier to upgrade from WiMax to TD-LTE than to LTE.
  • LTE Advanced: LTE Advanced is a further evolution of current LTE networks which brings with it theoretical peaks of 1GBps download speeds, increased spectrum efficiency(upto 3 times more bandwidth), and reduced latency. Like the upgrade from HSPA to HSPA+, a move from LTE to LTE-Advanced is also a software deployment upgrade.
  • TD-LTE will also see a shift to TD-LTE advanced in the future.


Advantages of LTE over HSPA+

  • The most obvious advantage is the higher data speeds
  • Much better spectrum efficiency
  • Far lower latency
  • LTE has a simpler architecture compared to an HSPA+ network

Advantages of HSPA+ over LTE

  • HSPA+ is an already established network, whereas complete LTE coverage still has a while to go
  • HSPA to HSPA+ evolution required much less investment in infrastructure and was less costly to upgrade as opposed to LTE which needs a completely new network built from the ground up.
  • LTE requires specific LTE radio featured devices, whereas HSPA+ is available to any user with a 3G enabled phone.

As you can see, LTE is definitely the way of the future, and the potential with this technology is incredible. But I still think there are a lot of factors that lead me to conclude that HSPA+ networks are certainly more than enough for now.

What are your thoughts? Is HSPA+ good enough for now? Is LTE not here fast enough? Let us know in the comments section below. We’d love to know what you think!


Born to avert another 26/11, Heuristics Info Systems offers location based security systems

Sometimes opportunities knock at our door at the wildest of circumstances and take us off guard. For Amit Dubey and his team members at Heuristics Info, this happened with 26\11 Mumbai terrorist attacks. During this unfortunate incident the police was late to learn about the attacks and in the interim Railway Protection Force (RPF) guards were left at the mercy of the AK47s against their normal weapons.


Heuristics Info System Pvt Ltd has emerged as a leading company in the field of location-based products, solutions and services. It offers VTS and Mobile Application software and provides unique cost effective quality solutions to various industry segments. The Heuristics team has an extensive experience in GPS Based Vehicle Tracking System (VTS) and Mobile Based Personnel Tracking Solutions, e-Beat, e-Investigation Solutions etc. Amit shares “In case of 26\11 attacks, management found out that the failure of beat operation co-ordination was because communication between RPF and Police was not made in time.”

Beat (patrol) is a very important activity of Police department, where constables at each station are assigned some important sensitive locations to patrol, such as hospitals, railway stations, bus stands, schools etc. They are supposed to keep an eye on these locations frequently, but in the former case there was no tool to ensure the patrol was done efficiently. To improve the scenario Punjab Police invited Heuristics Info to develop a tool to monitor their beat constables. Amit and his team members analyzed the whole situation and came up with Mobile Phone and Server based beat monitoring solution. It’s a client server based solution where a software runs in the background of the mobile phone which keep sending live location of a mobile to the server and if the mobile takes any image/video that also gets uploaded to the server instantly. This became a huge hit and subsequently they were recommended for e-governance award also. lt was deployed in Punjab Police as e-Beat/e-Investigation System on 6th Jan 2011. Following this success the startup started focusing on Private Industries and developed a very strong GPS/GIS Cloud based server platform which could track any GPS device available in the world.

Heuristics Info is led by Amit Dubey, as co-founder and CEO he has over 12 years experience in embedded and mobile software industry as senior manager with Samsung, ST-Micro and ST-Ericsson. He is also a renowned Crime Investigation Expert. Amit is well supported by Pradeep Rai (co-founder and CTO) and Rahul Shivhare. Pradeep has rich experience of 14+ years in Location Based Services and GIS Industry in Tele atlas Infotech, and TomTom. He also has expertise in developing highly optimized cloud based server solutions. While Rahul has 12+ Years in enterprise sales of Software Solutions, Experience with GPS, logistics and Fleet Management Industry. A total of 16 other members in the team also provide valuable support in strengthening the services.

The vision which was framed to help Indian Police Department was diversified to other business prospectus. Amit chips in “When we started developing the server solutions for various kinds ofebeatGPS tracking units, we realized the scalability potential of this business and we started identifying various gaps in this business. We thought of becoming number one GPS software service provider in India.” Their cloud based server now supports more than 150 different types of GPS trackers, these can be easily tracked on their server. They also offer a very specialized GPS Tracking Based Software Solution to Manufacturing Industries like Maruti and Transport Corporation of India (TCI), Coldex etc.

In August 2012 they had started office in Ghana and this year they have touched a partner count of 55 and achieved 800 + direct/indirect customers. Amit shares “The whole idea to select Africa (to expand our services) was to explore the under-developed markets. But we do have plans to expand to other countries as well. This year we opened an office in US and we are aiming for the same in UK as well.”

Heuristics was started with the initial savings from the founders, later they got a grant of 25 lakhs from Amity Incubator. They have been growing by 25-30% per month while focusing on the African market. Team Heuristics wish to touch a revenue count of five crores by the end of this financial year. They have also eyed to become a leader GPS software service provider in Africa by 2014/15.
