Largest Rifle In The World : The Tank Killer! What the Germans needed as much as tanks was something to stop the British and French tanks and this was the Mauser 13.2mm Tank Abwehr Gewehr Model 18 or “Mauser 1918 T-Gewehr.”
Known simply as the Tankgewehr, it was an upscaled bolt-action rifle that was based on the Mauser action. Unlike the Gewehr 98 – the standard service rifle used from 1898 to 1935, which featured an internal five round magazine – the T-Gewehr was a single-shot weapon that had to be manually loaded each tip. It also differed from other rifles of the era in that it had a pistol grip and bipod.
What the Tankgewehr lacked was anything to reduce the recoil, including a muzzle brake or even padded buttpad. Shooting multiple rounds could take a toll on the man charged with firing it. The rifle was developed after the British had launched the first full-scale tank offensive at Cambrai in the fall of November 1917, and pushed the Germans back some 20 kilometers.
The massive rifle was chambered to fire a powerful 13.2 TuF (Tank und Flieger-Tank and Aircraft), a .525-caliber jacketed, armor-piercing, steel-core cartridge. Effective range was about 500 meters, but gunners had to fire over iron sights.

Two to three T-Gewehr were issued per regiment, and each was operated by a two-man gun crew. One man would be the primary gunner and would carry the rifle along with twenty of the specially designed TuF rounds, while the second man in the team would carry two shoulder bags with twenty rounds in each, as well as an ammunition box that contained an additional seventy-two cartridges.
The rifle did a reasonably good job of stopping enemy tanks, which typically had just 12mm of armor protection at that point, but it was really too late to turn or even stop the tide. By the end of 1918, Germany surrendered. And the T-Gewehr became a forgotten rifle.
However, it was the only anti-tank rifle to see service in World War I. In addition there were later attempts – notably as the British Boys Anti-tank Rifle. Moreover, to upsize a rifle to take out a tank, but none were remotely as successful as the T-Gewehr.
