United States Army Engineer Command Vietnam

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.
