Most pieces of military equipment have PMCS charts used to go over every detail needed or noted to ensure the proper function of every mechanical item or non-mechanical surface.
Checks are also done at weekly, monthly, semi-annual, annual, or bi-annual intervals, depending on the specific part.
[1] Doing a PMCS check every time equipment is used may reduce the number of failures.
This reduces the number of injuries during training exercises, improve effectiveness in combat, and increase the operator's ability to implement their equipment.
[citation needed] A PMCS is required before a vehicle can be dispatched and before a piece of equipment, such as a weapon, can be issued.
