It's largely due to the fact that there is no standardization of the terminology.
Take the phrase "Secure a building" for example.
To the Army this means that you set a perimeter and make sure nothing goes in or out.
To the Marines, this means going in room by room, neutralizing all threats, setting a perimeter and god helps anything that comes near the place.
To the Navy it's turning off the lights and locking the door.
To the Air Force? They'll get a three year lease with an option to buy.
