How many soldiers were in a troop for World War 2?

Answer 1

A "troop" would normally indicate a single unit of a body of troops. However, the military use is as a subunit equivalent to a "platoon" consisting of two or more squads. A modern infantry platoon would typically be between 15 and 30 soldiers, and a squad between 8 and 12 soldiers.

In World War 2, however, the basic rifle squad consisted of 12 men, and there were usually 3 squads per platoon, which with command personnel made a platoon (troop) 45 to 50 men, commanded by a commissioned officer.

(With a squad leader and assistant squad leader, and two or more heavy weapons, such as the BAR and submachine gun, a squad would often split up and engage tactically in 6-man teams.)
