A simulation of the first anti-tank rifle against the British Mark IV tank at close range, with 0° and 45° impact angles. The projectile simulated is the Tank und Flieger Armour-Piercing bullet, with a hardened steel core. The simulation first presents it impacting the vertical front armour of the Mark IV from 50m, as if it was fired up from a trench. The Mark IV was one of the first tanks to ever enter service, in 1917, and was the most numerous British tank of WW1. Its armour protected it against machine gun and rifle bullets, as these were the main threats it faced upon entering service. The Tankgewehr M1918 was the direct counter to the tank, being the first dedicated anti-tank weapon to enter service. It was essentially a scaled up Mauser rifle, chambered for the high-calibre machine gun cartridge. Its armour-piercing projectile gave it sufficient power to deal with tanks at close-to-medium range, depending on the impact angle. For the simulation, a 450BHN steel model was used for the armour, with the ductility being slightly lowered from my 450BHN RHA model to account for poorer metallurgy of WW1 steel. It was only slightly lowered as to provide a good comparison with experimental results on modern 450BHN steel, tested by @ForgottenWeapons Therefore, depending on the actual properties of WW1 armour, the result may differ slightly, however the simulation is in close agreement with the only representative experiment available.
