Soldiers have nanomachines (in Metal Gear nanomachines can be replaced with magic) in them that work like ID tags and guns only work when they detect it

In a practical sense, all you need to prevent other people from using your guns is a lock. I put a lock on my closet. If the aren’t under my supervision, they’re behind at least one lock.
How do those guns work? I haven’t played the game.
