I saw something by Jeff Cooper saying how the military terminology differs between the branches.
It went something like this:
Ask a member of our military to "secure this".
Navy, turn off the lights and shut the door.
Army, Shut and lock all access, post a guard and prohibit entrance without proper clearance.
Airforce, Rent with option to buy.
Marines, assault with heavy fire, fortify and call in an air strike.
This is not exactly what was said, buy it's a paraphrase from what I remember.
I thought it was pretty funny.
