[PAR] [TLE] Anti-tank warfare [SEP] Anti-tank warfare arose as a result of the need to develop technology and tactics to destroy tanks during World War I.  Since the first tanks were developed by the Triple Entente in 1916 but not operated in battle until 1917, the first anti-tank weapons were developed by the German Empire.  The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside killing occupants.  Because tanks represent an enemy's greatest force projection on land, anti-tank warfare has been incorporated into the doctrine of nearly every combat service since.  Most predominant anti-tank weapons at the start of World War II were the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry as well as ground-attack aircraft. [PAR] [TLE] Mauser 1918 T-Gewehr [SEP] The Mauser 13 mm anti-tank rifle (, usually abbreviated T-Gewehr) was the world's first anti-tank rifle—the first rifle designed for the sole purpose of destroying armored targets—and the only anti-tank rifle to see service in World War I.  Approximately 15,800 were produced.
