[1616]. In marching a guard or a detachment of a guard the principles of [paragraph 1615] apply. "Eyes right" is executed only in the ceremonies of guard mounting and relieving the old guard. (54)
[1617]. If a person entitled to the compliment, or the regimental, battalion, or company commander, passes in rear of a guard, neither the compliment nor the salute is given, but the guard is brought to attention while such person is opposite the post of the commander.

[1618]. The commander of the guard will inspect the guard at reveille and retreat, and at such other times as may be necessary, to assure himself that the men are in proper condition to perform their duties and that their arms and equipments are in proper condition.

[1619]. The guard will not be paraded during ceremonies unless directed by the commanding officer. (57)
