A slang military command to prepare weapons for battle. No US weapon includes "lock and load" as one of the commands related to that weapon, nor is it a recognized range command
Lock and load, boy, lock and load.
"Load and lock" was a military command in the United States. Originally, this order referred to the operation of the M1 Garand rifle. The phrase describes the insertion of a clip of ammunition into the rifle, loading the clip, and locking the bolt forward (which forces a round into the chamber, readying the rifle for use). Thus the phrase is an example of the rhetorical device hysteron proteron
