Corps of Engineers

Worn from:
3 February 1971 - 30 April 1972.

The colors scarlet and white refer to the Corps of Engineers,
while scarlet and yellow are the colors of the flag of the
Republic of Vietnam. The three colors combined (scarlet, white,
and yellow) represent the engineer command's commitments in combat
engineering, construction, and facilities engineering services
throughout the Republic of Vietnam. The two crusaders' swords
symbolize the roles of the engineer command with its two major
military arms, the eighteenth and twentieth Engineer Brigades,
in military assistance and defense of the Republic of Vietnam.
The hexagonal figure is a fortress viewed from above. The upper
three turrets represent the three Engineer Groups of the Eighteenth
Engineer Brigade, which operated in the upper half of the Republic of
Vietnam, and the lower three turrets the three engineer groups of the
Twentieth Engineer Brigade whose area of operations was the lower half
of the Republic of Vietnam. The division of the fortress into three
elements by the superimposed swords refers to the three engineer districts
of North, Central, and South Vietnam.
