Training Circular TC 3-22.6 Guard Duty January 2017 This manual is for personnel concerned with the organization and functions of interior and exterior guard. It includes orders, countersigns, parole words, and the responsibility of the main guard including duties of personnel and the formal method of mounting the guard. The manual also discusses the duties and composition of special guards. This manual is a guide, and because all possible situations and eventualities cannot be foreseen or covered by the manual, great reliance must be placed upon the application of sound judgment by all members of a guard and by all security personnel, which ultimately leads to the ethical application of force when warranted. In situations not covered by this manual and where doubt arises as to the proper action to be taken, as an Army professional, the individual must consider the mission, their orders and apply sound judgment in making the required decision(s).
