A Marine Corps Chief Warrant Officer 3 (CWO-3) wears pin-on metal grade insignia on the collars of short- and long-sleeve khaki shirts, the Marine Corps Combat Utility Uniform, and the camouflage Maternity coat. Like the Warrant Officer 1 insignia, the CWO-3 rank design features two scarlet enamel blocks superimposed evenly on top on a bar, but the CWO-3 rank uses a silver bar rather than gold.
The CWO-3 collar grade insignia is oriented so that the long axis of the device is parallel to the front edge of the collar; the device is centered between the top and bottom edges of the collar with its bottom one inch from the front of the edge of the collar.
Customers purchasing the CWO-3 collar grade insignia might wish to add
CWO-3 cap rank insignia (identical to these devices but sold individually) or the
larger coat rank insignia (3/8-inch longer than the collar insignia and sold in pairs) to their shopping carts.
