“Drill and Ceremonies”
by the Department of the Army (FM 3-21.5)
“This field manual provides guidance for Armywide uniformity in the conduct of drill and ceremonies. It includes methods of instructing drill, teaching techniques, individual and unit drill, manual of arms for infantry weapons, and various other aspects of basic drill instruction. This manual is designed for use by soldiers of all military occupational skills, to include the new soldier in the initial entry training environment. Since all situations or eventualities pertaining to drill and ceremonies cannot be foreseen, commanders may find it necessary to adjust the procedures to local conditions. However, with the view toward maintaining consistency throughout the Army, the procedures prescribed herein should be followed as closely as possible.”
