151.  Color sentinels are not placed on the regular reliefs, nor are their posts numbered.  In calling for the corporal of the guard, they call:  “Corporal of the guard.  Color line.”

152.  Officers or enlisted men passing the uncased colors will render the prescribed salute.  If the colors are on the stacks, the salute will be made on crossing the color line or on passing the colors.

153.  A sentinel placed over the colors will not permit them to be moved except in the presence of an armed escort.  Unless otherwise ordered by the commanding officer, he will allow no one to touch them but the color bearer.

He will not permit any soldier to take arms from the stacks or to touch them except by order of an officer or noncommissioned officer of the guard.

If any person passing the colors or crossing the color line falls to salute the colors, the sentinel will caution him to do so, and if the caution be not heeded he will call the corporal of the guard and report the facts.

SECTION 9.  PRIVATES OF THE GUARD.

154.  Privates are assigned to reliefs by the commander or the guard, and to posts usually by the corporal of their relief.  They will not change from one relief or post to another during the same tour of guard duty unless by proper authority.

SECTION 10.  ORDERS FOR SENTINELS.

155.  Orders for sentinels are of two classes:  General orders and special orders.  General orders apply to all sentinels.  Special orders relate to particular posts and duties.
