For some reason, infantry hitching a ride on tanks is a tactic stereotypically associated only with the USSR. In reality, infantry from all nations did this, even those that produced APCs such as Germany. This was not an ad hoc maneuver either, but a tactic officially described in field manual. For instance, manual 130/2b "Motorized company of an infantry motorized division" signed by General Walther von Brauchitsch on October 11th, 1941, states:
"190. To defeat an enemy positioned in cover, it is sometimes reasonable to mount troops on tanks that would be able to defeat the concealed enemy firing from their vehicle or in close combat. In this case, equip them with hand grenades, pistols, submachine guns, and flare guns.
Communication with tanks is achieved through the normal signals (attachment #2). However, regardless of this, one must carefully negotiate cooperation between the tank crew and the troops that ride the tank ahead of time."
