WWII
Sherman
The Sherman tanks were some of the most common U.S tanks of world war 2 and participated in many battles. Although German Panzers and Tiger tanks were more powerful, Shermans became well known.
WWI
German A7V
A big, slow but heavily armed tank the A7V can have up to 7 machine guns and a main turret. Because of this, it needs a big crew. What a fatty! only 20 of these were made.
Mark 5 British tank
The Mark series of tanks were the first tanks ever made. Although not very effective, these tanks opened up the door for newer, better tanks
