Yellow, blue, and red are colors of branches from which
armored units were formed representing, as they did, cavalry,
infantry, and artillery. The tank tread, gun, and lightning

now in army green colors, is the unit's designation.
The school is located at Fort Knox, Kentucky.
Its establishment was authorized on 19 September 1940.

The motto of the school is "Forge the Thunderbolt,"
indicating the basic philosophy of armor -- machines of war
are important but success on the battlefield ultimately rests
on the men who use those machines.
