In the military of the United States and other militaries, the Color guard carries the National Color and other flags appropriate to its position in the chain of command. Typically these include a unit flag and a departmental flag (Army, Marines, Navy, or Air Force). In addition to the flag bearers, who are positioned in the center of the color guard, there are two individuals who carry rifles.
Traditionally, the unit's sergeant major is responsible for the safeguarding, care, and display of the organizational colors. He is also responsible for the selection, training, and performance of the members. The Color guard consists of enlisted members and is commanded by the senior (Color) Sergeant, who carries the National Color and gives the necessary commands for movements and rendering honors during drill exercises or parade ceremonies.
Being assigned to the Color guard is considered an honor due to the fact that these individuals present and carry the symbols of their unit and country. 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.
The Color guard is formed and marched in one rank at close interval (shoulder-to-shoulder). Since the National Colors must always be in the position of honor on the right, 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.
Other drill movements performed by the Color guard include presenting arms, left and right wheel marches, eyes right (upon passing the reviewing stand during a parade), casing/uncasing the Colors, and fixing/unfixing bayonets (by the arms bearers).
Civilians and those otherwise not in uniform are expected to stand at the position of attention with their right hand placed over their heart for the same period.
