An NCO supervisor must be present when soldiers arm live mines. He ensures that soldiers adhere to the proper procedures and regulations. Only one soldier arms a mine at any given time. Personnel disarm one mine before arming the next one. Personnel never remove the positive safety pin from the M16 AP mine during live-mine training.
Instructors inspect fuses and mines for serviceability before starting practice.
Instructors inspect mines and their components for damage and excessive wear after each student has gone through the station. Replace the mine and the fuse if damage or wear is found. Ear protection is not permitted in the arming bays. Instructors post guards at all entrances to the range. The guards communicate with the RSO by radio, wire, voice, or signal.
