U.S. ARMY 21ST THEATER SUSTAINMENT COMMAND COMBAT SERVICE ID BADGE (CSIB)

What is explicitly stated on the unit crest of 21st Theater Sustainment Command—“First In Support,” which is the Unit Motto—is portrayed via symbolic imagery on the CSIB you see here. The figure in the middle of the shield is a millrind, an iron support used to hold up the stone that turns on its axle as it grinds the wheat on the bed stone. As a heraldic charge, it symbolizes support; when combined with the fact that it is essential to the grinding of wheat and thus the making of the worldwide staple food bread, the image reinforces the concept of vital and complete support provided by the Command.
