The design is taken from the flag of the United States Army along
with the inscription. With the advent of subdued insignia in 1967,
the colors were changed to Olive Drab and black. The central element
of the design is a Roman cuirass, a symbol of strength and defense.
The rattlesnake, and the motto "THIS WE'LL DEFEND," signifies the Army's
constant readiness to defend and preserve the United States. The torch
represents the knowledge imparted by the instructor to his soldiers.
