Eyes Right Procedure
When marching, the preparatory command Eyes is given as the right foot strikes the marching surface and the command of execution RIGHT is given the next time the right foot strikes the marching surface.
On the command of execution RIGHT, all men, except the right file, turn their heads and eyes to the right and align themselves on the right file while continuing to march.
Men in the right file do not turn their heads and eyes but continue looking straight to the front and maintain correct distance.
Only the platoon leader salutes.
