The Q-NET is an add-on armor kit developed by QinetiQ to counter the threat of rocket-propelled grenades.
The Q-Net is an armor system that stands off from the vehicle's hull and "catches" the RPG before it hits the outside of the vehicle itself, using metal nodes connecting the net to disrupt the fusing of the warhead. The Q-Net is similar to other add-on systems like slat armor cages, but with additional benefits of being cheaper and 50-60% lighter than slat, allowing it to be integrated on light vehicles that cannot support slat such as Humvees. Because it is lighter, it reduces power train stress and fuel consumption, while giving equal or greater protection than bar armor. It is fully modular with a hook-and-loop installation method, allowing the system to be configured to different platforms. The net gives 360-degree coverage and can even provide overhead protection. [1]
The Q-Net was first sent to combat in Afghanistan in 2010. When soldiers saw the armor system, they were skeptical and concerned about its effectiveness. On September 19, a vehicle patrol equipped with Q-Nets was ambushed. At less than 100 meters distance, insurgents fired a volley of RPG rounds, followed by machine gun fire and then another RPG. The soldiers moved forward of the ambush and repelled the attack. Following the firefight, they found that the vehicles had taken three direct hits from RPGs and had not penetrated. They detonated at the nets, stopping them from penetrating the armor. One soldier commented, “All of the soldiers whose vehicles were hit by RPGs are alive today and still in the fight.” [2]
Following initial combat performance, 7,500 kits were ordered and produced at a rate of 1,000 per month. [3] In February 2011, the U.S. Army ordered 829 nets for use on the Navistar MaxxPro. [4] In May 2012, QinetiQ received a contract for 420 more Q-Net kits. They have been used on Humvees, RG-31s, M-ATVs, and other armored vehicles. [5] On 6 December 2013, QinetiQ North America was awarded an $18.3 million contract to provide Q-Nets to protect hundreds of M-ATVs. [6]
By September 2012, 11,000 Q-Net kits had been delivered. At the same time, QinetiQ unveiled an improved version, the Q-Net II. Upgrades included the probability of defeating a warhead being further increased and even more weight reductions. It gives improvements to survivability and platform performance. [3]
The High Mobility Multipurpose Wheeled Vehicle is a family of light, four-wheel drive, military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the original jeep, and others such as the Vietnam War-era M151 Jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations. The Humvee saw widespread use in the Gulf War of 1991, where it navigated the desert terrain; this usage helped to inspire civilian Hummer versions. The vehicle's original unarmored design was later seen to be inadequate, and was found to be particularly vulnerable to improvised explosive devices in the Iraq War. The U.S. hastily up-armored select models and replaced front-line units with the MRAP. Under the Joint Light Tactical Vehicle (JLTV) program, in 2015 the U.S. Army selected the Oshkosh L-ATV to replace the vehicle in front-line U.S. military service.
A rocket-propelled grenade (RPG) is a shoulder-fired rocket weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front.
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems.
The Stryker is a family of eight-wheeled armored fighting vehicles derived from the Canadian LAV III. Stryker vehicles are produced by General Dynamics Land Systems-Canada (GDLS-C) for the United States Army in a plant in London, Ontario. It has four-wheel drive (8×4) and can be switched to all-wheel drive (8×8).
Military vehicles are commonly armoured to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships.
BAE Systems Platforms & Services is a wholly owned subsidiary of BAE Systems Inc. and is a large provider of tracked and wheeled armored combat vehicles, naval guns, naval ship repair and modernization, artillery and missile launching systems, advanced precision strike munitions and ordnance, and other technologies for U.S. and international customers.
The M1117 Guardian, also denoted Armored Security Vehicle (ASV), is an internal security vehicle based on the V-100 and V-150 Commando series of armored cars. It was developed in the late 1990s for service with the United States' Military Police Corps. The first prototypes appeared in February 1997 and serial production of the M1117 commenced between 1999 and early 2000.
An infantry mobility vehicle (IMV) is a wheeled armored personnel carrier (APC) serving as a military patrol, reconnaissance or security vehicle. Examples include the ATF Dingo, Iveco LMV, Oshkosh M-ATV, AMZ Dzik, AMZ Tur, Mungo ESK, and Bushmaster IMV. This term also applies to those vehicles fielded as part of the MRAP program.
The Joint Light Tactical Vehicle (JLTV) is a U.S. Army, U.S. Marine Corps and Special Operations Command program to partially replace the Humvee fleet with a family of more survivable vehicles having a greater payload. Early studies for the JLTV program were approved in 2006. The JLTV program incorporates lessons learned from the earlier Future Tactical Truck Systems program and other associated efforts.
Mine-Resistant Ambush Protected is a term for United States military light tactical vehicles produced as part of the MRAP program that are designed specifically to withstand improvised explosive device (IED) attacks and ambushes. The United States Department of Defense MRAP program began in 2007 as a response to the increased threat of IEDs during the Iraq War. From 2007 until 2012, the MRAP program deployed more than 12,000 vehicles in the Iraq War and War in Afghanistan.

The International M1224 MaxxPro MRAP is an armored fighting vehicle designed by American company Navistar International's subsidiary Navistar Defense along with the Israeli Plasan Sasa, who designed and manufactures the vehicle's armor. The vehicle was designed to take part in the US military's Mine Resistant Ambush Protected vehicle program, led by the US Marine Corps, as well as a similar US Army-led Medium Mine Protected Vehicle program.
Slat armor, also known as bar armor, cage armor, and standoff armor, is a type of vehicle armor designed to protect against high-explosive anti-tank (HEAT) attacks, as used by anti-tank guided missiles (ATGMs) and rocket-propelled grenades (RPGs).
The Humvee replacement process was an effort by the U.S. military to replace the current AM General Humvee multi-purpose motor vehicle. The Humvee had evolved several times since its introduction in 1984, and is now used in tactical roles for which it was not originally intended. The U.S. military pursued several initiatives to replace it, both in the short and long term. The short-term replacement efforts utilize commercial off-the-shelf (COTS) vehicles, while the long-term efforts focused on building requirements for the Humvee replacement and technology research and evaluation in the form of various prototype vehicles.
The Oshkosh M-ATV is a mine-resistant ambush protected (MRAP) vehicle developed by the Oshkosh Corporation for the MRAP All Terrain Vehicle (M-ATV) program. Intended to replace M1114 HMMWVs (Humvee), it is designed to provide the same levels of protection as the larger and heavier previous MRAPs, but with improved mobility.
Quick Kill is an active protection system (APS) designed to destroy incoming anti-tank missiles, rockets, and grenades. The Quick Kill system is designed and produced by Raytheon for the U.S. Army. The Quick Kill system was part of the United States Army's Future Combat Systems.
Iron Curtain was an active protection system (APS) created in 2005 and designed by Artis, an American technology development and manufacturing firm. The system deactivated threats, such as rocket-propelled grenades (RPG) and other shoulder-launched missiles.
The Oshkosh L-ATV is a light utility/combat multi-role vehicle that won the US military's Army-led Joint Light Tactical Vehicle (JLTV) program. In the very early stages of the program it was suggested that JLTV would replace the AM General High Mobility Multi-purpose Wheeled Vehicle (HMMWV) on a one-for-one basis. It is now suggested that the JLTV will partly replace the HMMWV, not replace it on a like-for-like basis.
The Armor Survivability Kit (ASK) is an armor kit developed by the U.S. Army Research Laboratory (ARL) in 2003 to protect vehicles like the Humvee from small arms, explosive device fragments, and rocket-propelled grenades (RPGs).
