1918 Mauser Tank Gewehr
The Mauser 1918 Tank Abwehr Gewehr was the world's first purpose-built anti-tank rifle, developed in response to early tank warfare. Chambered in the powerful 13.2mm TuF cartridge, it could penetrate 20mm of armor at 100 yards. Despite its immense power and 41-pound weight, it was produced in large numbers and influenced later designs like the .50 BMG.
