## Community notes

Lock prevents AI persons mounting or dismounting vehicles when ordered to do so and players are prevented from doing both too, but AI will still dismount when a vehicle is damaged.

If an AI group (e.g Mechanized Infantry) has its vehicle locked with its crew in it, it will mount or dismount it anyway. But a player in this group won't be able to enter the vehicle.
