GROM is at the forefront in the global war against terrorism. They are Poland's secret weapon as well as a valued ally of western nations. They have trained with the best in the world - the SAS and U.S. Navy Seals, among others. What makes GROM so unique is that they are a hybrid elite force, integrating the most effective and most deadly tactics acquired from each of the top special forces around the world. GROM is so highly rated that the U.S. Navy Seals have called them the "Polish Navy Seals". GROM and the Navy Seals have collaborated closely in many international missions, including Operation Iraqi Freedom.

As part of this special series, we take a look at some of the most powerful weapons that have been produced during the past several years. Because the field of weaponry is so vast, only a few can be presented here. Bear in mind that the specifications that are to follow are far from comprehensive, but rather rudimentary and intentionally incomplete. Nevertheless it is meant to be a showcase of lethal weapons; weapons that are part of the arsenal of some of the world's special forces, including GROM.



The Bushmaster ACR (Adaptive Combat Rifle) is a relatively new design in the arsenal of weapons and is being used by the United States Army, as well as by GROM forces. The design is borrowed from the Magpul Masadan, which is an amalgamation of the best features of rifle designs recently developed: the short-stroke gas system from the Armalite AR-18; the upper receiver, charging handle location, from the FN SCAR; the liberal use of polymer components from the Heckler & Koch G36/XM8; the trigger pack from the M16/AR-15; and the barrel from the M16. The Busmaster also includes a quick-change barrel/trunnion system, adjustable gas regulator, non-reciprocating charging handle and storage compartments in the stock and grip. The weapon's caliber can easily be changed by replacing the bolt head, magazine and barrel. Incidentlaly the rifle was named after the Siege of Masada, though Magpul Industries is not Jewish-owned or Israeli-backed.

The Heckler & Koch MP5, the "Maschinenpistole 5" is a 9mm submachine gun developed in the 1960s by a team of German engineers for the small arms manufacturer Heckler & Koch GmbH (H&K)and Oberndorf am Neckar. The MP5 is still being manufactured and is one of the most widely used machine guns in the world, used by countless number of military forces, police units and intelligence and security organizations. In the 1990s Heckler & Koch developed a new successor to the MP5, called the Heckler & Koch UMP, both of which remain in wide production. There are virtually dozens of variants of the MP5 on the market - for example the MP5A2, which is a lightweight, air-cooled, selective fire delayed blowback operated 9x19mm Parabellum weapon with a roller-delayed bolt. It fires from a closed bolt (bolt forward) position. The MP5-N ("N" for Navy)was developed especially for the United States Navy in 1986. This particular model has a collapsible stock, a tritium-illuminated front sight post and a 225mm (8.9 in) threaded barrel for use with a stainless steel sound suppressor (made by Knight's Armanent Company) combined with quieter subsonic ammunition. The MP5K (K for the German word kurs, meaning "short") was developed in 1976. It was a shortened version of the MP5A2 and was designed for battle in close quarters, ideally used by clandestine operatives and special services. The MP5K model does not have a shoulder stock (the receiver end is covered with a flat end cap, featuring a buffer on the inside and a sling loop on the outside) and the bold and receiver were shortened at the rear. It produces a higher rate of fire than the MP5. The barrel, cocking handle and its cover were shortened and a vertical foregrip was used to replace the standard handgard. The barrel ends at the base of the foresight preventing the use of any kind of muzzle device. The MP5 is being manufactured under license in several countries including Greece, Iran, Mexico, Turkey, Pakistan, and the United Kingdom. It is the Ultimate weapon for battle in close quarters. It's lightweight, small, but wields deadly accuracy.

FN F2000

The FN F2000 was designed by Belgian manufacturer, FN Herstal and made its debut in March 2001 at the IDEX defense exhibition at Abu Dhabi, in the United Arab Emirates.

The F2000 is a modular weapon system. Its principal component is a compact 5.56x45mm NATO caliber assault rifle configured in a bullpup layout. The F2000 is a selective fire weapon operating from a closed bolt. The rifle consists of two main assemblies: the barreled receiver group and the frame, coupled together by means of an axis pin located above the trigger guard. The barrel group has an integral ML-STD 1913 Picatinny rail used to mount optical sights. The frame or lower receiver contains the trigger group, the bolt and bolt carrier assembly, return mechanism and magazine well. The removable handguard is installed in front of the trigger which completes and enclosed the trigger guard.

The F2000 is a gas operated, fully automatic and ambidextrous bullpup rifle. One of the modules developed for the F2000 system is a proprietary lightweight 40 mm under-slung GL 1 grenade launcher that uses standard low-velocity 40x46mm grenades. The launcher is a single-shot breech-loaded pump-action weapon with a barrel that slides forward for loading and unloading (like the M203 grenade launcher), locked by axial rotation of the barrel.

When Poland became a member of NATO in 1999 the Polish Armed Forces were required to produce firearms that were compatible with NATO standards. In the early 2000s, Aleksander Lezucha embarked on a joint venture with the Polish Science Research and Information Technology Ministry to create a new standard sniper rifle. During the development stage the rifle was named "Alex" but received the military designation of "Bor" thereafter.

The Bor is a bullpup-configuration bolt-action magazine-fed sniper rifle. The barrel length (of 680 mm, or 26.8 in) provides increased accuracy while minimizing the overall length of 1,038 mm (40.9 in). Weight has been reduced by the use of a free-floting fluted barrel, without sacrificing accuracy. The muzzle is fitted with a double-baffle muzzle brake, which is claimed to reduce recoil by up to 30%. The "in-line" design of the barrel-receiver group also directs recoil rearwards in a straight line, minimizing muzzle flip. A sturdy adjustable bipod is fitted to the front of the fore-end. The rifle features a fully adjustable buttstock and cheek riser. A folding/adjustable monopod located behind the magazine on the inside of the buttstock can be used to support the rifle in firing position during extended periods of deployment. No iron or emergency sights are provided; a MIL-STD-1913 Picatinny rail is mounted above the centerline of the barrel, over the receiver area for mounting various optical sights. The standard telescopic sight is a Leupold 4.5-14x50, with sight grid mil-dot reticle, parallax correction and an adjustment range of 100 MOA.

These sniper rifles are developed by SAKO, a Finnish firearm manufactuer. The TRG-22 was designed to fire standard.308 Winchester ammunition, while the TRG-42 was designed with a larger action and barrel to fire more powerful .300 Winchester Magnum and .338 Lapua Magnum ammunition. The SAKO has a folding stock, and are normally fitted with muzzle brakes to reduce recoil, jump and flash. The muzzle brakes vent sideways and are detachable. Most are fitted with a Zeiss or Scmidt & Bender PM II telescopic sight with either fixed or variable power of magnification. However, variable telescopic sights can be fitted for operators needing more flexibility to shoot at variable ranges, or when a wider field of view is required.

What is unique about the TRG is that it is a purpose-designed sniper rifle rather than an accurised version of an existing rifle. The heart of the TRG system is a cold-hammer forged receiver and barrel, which provide the maximum strength at minimum weight making it exceptionally resistant to wear. The "resistance free" bolt has three massive lugs and requires a 60 degree bolt rotation and a 98 mm (3.86 in) bolt throw for the short and 118 mm (4.65 in) bolt throw for the long bolt-action - features that should be appreciated by the shooter during multiple firings that require rapid projectile placement on the target.

AT-4 Light Anti-Tank Rocket
The AT4 built by the Swedish, Saa Bofors Dynamics (formerly Bofors Anti-Armour Systems), is an 84-mm unguided, portable, single-shot recoilless smoothbore weapon. The AT 4, as well as its variants, AT4 CS, AT4CS have had considerable success and has become one of the most commonly used anti-tank weapons in the world.

The designation "CS" (confined space) refers to the propellant charge which makes it possible to operate the AT effectively within buildings in an urban environment. It enables infantry units a means to destroy, or disable armored vehicles and fortifications. But it is not designed to defeat a modern MBT (main battle tank). The launcher and projectile are manufactured prepacked, and issued as a single unit of ammunition with the launcher discarded after a single use.

The AT4 took many of its design features from the Carl Gustav, and may be considered a disposable, low cost alternative to a Carl Gustav recoilless rifle. It operates on the principle of a recoilless weapon, where the forward inertia of the projectile is balanced by the mass of propellant gases ejecting from the rear of the barrel. But unlike the Carl Gustav, which uses a heavier and more expensive steel tube with rifling, the disposable AT4 design greatly reduces manufacturing costs by using a reinforced smoothbore fiberglass outer tube. Since recoilless weapons generate almost no recoil, a relatively large projectile can be fired which would otherwise be impossible in a man-portable weapon.

To fire the AT4, the gunner must first remove the safety pin located at the rear of the tube, thereby unblocking the firing rod. He then takes a firing position ensuring that no one is present in the back blast area. If firing from the prone position (lying on his stomach) he must also place his legs well to the side to avoid burning himself. Then the gunner moves back the front and rear sight covers, allowing the sights to pop up into their firing positions. After firing, the AT4 is discarded. Unlike the heavier Carl Gustav, the AT4 outer tube is built only to take the stress of one firing and is not reusable and cannot be reloaded like the Carl Gustav.

Accuracy International Arctic Warfare Magnum Folding (AI AWM F 300WM) .300 Winchester Magnum / 7.62x63 sniper rifle

The AWM (Arctic Warfare Magnum) is a sniper rifle manufactured by Accuracy International. It is also known by the acronym AWSM (Arctic Warfare Super Magnum), which typically denotes the .338 Lapua Magnum version.

The AWM rifle is a variant of the British Accuracy International Arctic Warfare, and has a longer bolt to accomodate larger magnum-length cartridges such as the .300 Winchester Magnum and the .338 Lapua Magnum, that are approved by NATO standards. The AWM has a detachable box magazine which holds five rounds. Muzzle brakes are fitted to reduce recoil, jump and flash and act as a base for optional iron sights and suppressors.

Normally, the AWMs are outfitted with a Schmidt & Bender PM II 10x42/MILITARY MK II 10x42 telescopic sight with 10x fixed power of magnification. However, a Schmidt & Bender PM II/MILITARY MK II with variable magnification of either 3-12x50, 4-16x50 or 5-25x56 can be used if the operator wants more flexibility to shoot at varying ranges, or when a wide field of view is required. Accuracy International actively promotes fitting the German made Schmidt & Bender PM II/MILITARY MK II product line as sighting components on their rifles, which is rare for a rifle manufacturer. The German and Russian Army preferred a telescopic sight made by Zeiss over Accuracy International's preference.

The AWM rifle is normally supplied in a metal transit case together with scope, mount, butt spacers, bipod, spare magazines, sling, cleaning and tool kits.

Spike is a fourth generation man-portable, fire-and-forget, anti-tank guided missile with tandem-charged HEAT warhead, developed and designed by the Israeli company Rafael Advanced Defense Systems and in service with numerous countries.

As well as engaging and destroying targets within the line-of-sight of the launcher ("fire-and-forget"), some variants of the missile are capable of making a top-attack profile through a "fire, observe and update" guidance method - the operator can track the target, or switch to another target, optically through the trailing fiber-optic wire while the missile is climbing to altitude after launch. This is similar to the lofted trajectory flight profile of the US FGM-148 Javelin.

The missile is a fire-and-forget missile with lock-on before launch and automatic self-guidance and equipped with an imaging infrared seeker, that is available for medium, long, and extended range missiles.

Spike is connected by a fiber-optical wire that is spooled out between the launch position and the missile. It allows the operator to obtain a target if it is not in the line of sight of the operator at the time of launch, permits switching targets while in flight, and is capable of compensating for the movement of the target if the missile is not tracking the target for some reason. Hence, the missile can be fired speculatively for a target of opportunity, or to provide observation on the other side of an obstacle. The missile has a soft launch capability - the motor firing after the missile has left the launcher- which allows for the missile to be fired from confined spaces, which is a necessity in urban warfare.

The missile uses a tandem warhead - two shaped charges, a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate the underlying armor. Currently, it is replacing aging second generation anti-tank missiles like the MILAN and M47 Dragon in the armies of the user nations.

Spike can be operated from the launcher by infantry, or from mounts that can be fitted to vehicles such as fast attack vehicles, APCs or any utility vehicle.
