Color Guard, Color Guard

Depending on the circumstance and subject to the orders of their commander, members may wear full dress or less formal uniforms. It is mandatory for all members of the Color guard to wear headgear, for example, a garrison cap, beret, or service cap. On occasion, certain color guards can be horse-mounted.

Since the National Colors must always be in the position of honor on the right, FM 22-5, Appendix E, Section 4 (United States Department of the Army) the Color guard must execute a special movement to reverse direction. It does not execute rear march, nor does it execute about face. Rather, it performs a maneuver derived from the standard countercolumn command, generally known as counter march or colors reverse march.
