Change Step.
[73.] Being in march: 1. Change step, 2. MARCH.
At the command march, given as the right foot strikes the ground, advance and plant the left foot; plant the toe of the right foot near the heel of the left and step off with the left foot.
The change on the right foot is similarly executed, the command march being given as the left foot strikes the ground.
MANUAL OF ARMS.
[74.] As soon as practicable the recruit is taught the use, nomenclature ([Pl. I]), and care of his rifle; when fair progress has been made in the instruction without arms, he is taught the manual of arms; instruction without arms and that with arms alternate.
[75.] The following rules govern the carrying of the piece:
First. The piece is not carried with cartridges in either the chamber or the magazine except when specifically ordered. When so loaded, or supposed to be loaded, it is habitually carried locked; that is, with the safety lock turned to the "safe." At all other times it is carried unlocked, with the trigger pulled.
Second. Whenever troops are formed under arms, pieces are immediately inspected at the commands: 1. Inspection, 2. ARMS; 3. Order (Right shoulder, port), 4. ARMS.
A similar inspection is made immediately before dismissal.
