A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a maroon Greek cross charged with a white disc bearing a gold star, all above a gold grizzly bear standing on four feet in base in front of a light green field and a gold setting sun, the top rays of the sun terminating in back of the cross; all enclosed by a triple-arched maroon scroll inscribed "COMMAND" on the left side and base, "GUIDANCE" on the top, and "CONTROL" on the right side and base, all letters gold.
Maroon and white are the colors used for the Army Medical Department. The grizzly bear and setting sun are suggested by the crest for the California Army National Guard. The gold star refers to the unit's location at Sacramento, the capital of California. Additionally, the sun and star, symbols of command, guidance, and control, allude to the organization's motto. The cross, an emblem of aid and assistance, signifies the medical mission of the unit.
The distinctive unit insignia was originally approved for the 175th Medical Group on 1 February 1972. It was redesignated for the 175th Medical Brigade on 4 March 1976.
