anti-materiel rifle

Although not originally designed for use against human targets, the bullet mass and velocity of anti-materiel rifles gives them exceptional long-range capability even when compared with designated sniper rifles. Anti-materiel rifles are made in both bolt-action and semi-automatic designs. The anti-materiel rifle originated in the anti-tank rifle, which itself originated during World War I. While modern tanks and most other armored vehicles are too well protected to be affected by anti-materiel rifles, the guns are still effective for attacking unarmored or lightly armored vehicles. They can also be used against stationary enemy aircraft, missile launchers, radar equipment, unexploded ordnance, small watercraft, communications equipment, crew-served weapons and similar targets. Their value lies in their ability to precisely target and disable enemy assets from long range at relatively low cost.

The need for anti-tank rifles was first encountered by the Germans when faced with the British Mark 1 tank. The Mark I could cross ditches up to 9 ft wide, which made it a major threat to infantry in trench defenses. As a counter, the Germans first used "direct fire mortars", which were mortars aimed at low angles pointing towards enemy tanks. Later, the Germans developed the T-Gewehr anti-tank rifle, which can be credited with being the first anti-materiel rifle. The rifle was designed to penetrate the thick armor of the British tanks. The rifle weighed when loaded, fired a 13.2 mm round weighing, and had an effective range of about. This weapon had a two-man crew: one to load and the other to fire the weapon, although they often switched roles. The recoil of this weapon was so high that it was known to break collar bones and dislocate shoulders. The rifle fired a steel core armor-piercing round specifically designed to be used with this rifle.

In September 1939 Polish army used the successful wz. 35 anti-tank rifle, around 800 of which were captured by Germans and put into service as Panzerbüchse 35(p). The British Boys anti-tank rifle was used to great effect against lightly armored tanks, but was soon replaced by the PIAT due to its ineffectiveness against more heavily armored tanks. The PTRD-41 and PTRS-41 anti-tank rifles were used by the Soviets on the Eastern Front. Germany used the Panzerbüchse 39, while Japan used the Type 97 automatic cannon, though the latter became obsolete by 1942. Notably, the United States did not develop or field any anti-tank rifles during the war, choosing instead to use explosive anti-tank weaponry such as the M1 Bazooka (though Swiss anti-tank rifles were trialed). One anti-tank rifle used was the Lahti L-39, a Finnish anti-materiel rifle. One version was designed to fire a 13.2 mm cartridge and another a 20 mm cartridge. There was debate over which was more effective at piercing armor. Some argued that the smaller cartridge travelled faster and could penetrate deeper into the armor, while others believed that the higher caliber rounds would cause greater damage. The weapon was quite heavy at and had an 88 in barrel, and it carried the nickname "the elephant gun".

During the Cold War, the Barrett M82 rifle was produced by the United States, and was chambered to fire a.50 BMG (12.7×99mm NATO) round. This weapon was sold by the U.S. to Swedish forces. An unusual silenced rifle, the Swiss G150 Präzisionsgewehr using a 10.4x33mmR carbine cartridge was issued to the P-26 stay-behind organization as a low-level anti material weapon to sabotage potential Soviet occupiers equipment up to 200m such as radio antennas, radar installations etc. The M82 rifle first saw action in the early 1990s, during the Gulf War. The U.S. Marine Corps initially purchased around 125 M82 rifles; orders from the Army and Air Force followed. These weapons were used with rounds such as armor piercing incendiary rounds (API) which were effective against such targets as buildings, trucks, and parked aircraft. The purpose of this round was to penetrate non-armored vehicles and burst into flames on impact. Saboted light armor penetrator ammunition was also used in anti-materiel rifles during the conflict.

As such, modern day anti-materiel rifles are no longer used in an anti-tank capacity, and generally used to penetrate light armor vehicles or for its barrier-blind capabilities against targets behind concrete barricades and buildings; as well as being used to destroy unexploded ordnance. Additionally, modern anti-materiel rifles are frequently used as sniper rifles against personnel targets, due to their long range, relatively low cost of construction for craft-produced models, and robust penetrating capabilities. They have seen frequent use in Syria and Iraq as a counter-VBIED weapon system, due to their greater ability to penetrate uparmored VBIED threats that standard rifle calibers used by designated marksmen (typically 7.62×54mmR and 7.62×51mm) are not able to reliably stop.
