The reason I'm yours is why because I was fascinated by tanks and that was used in war. like the t34 85that I drew was a  tanked up the Russians use to push back Nazi army. The tiger one was a late tank that the Germans use for the Eastern Front  because it needed a big gun to push through the Russians armored tanks. J Panther was a tank destroyer that the Germans used to stay in small places to snap out enemy tanks.  the M1 Abrams is a u.s. modern-day tank is it currently in combat and the Middle East.
