Yes, you've got to have terminology to have a proper army. You can't just go round talking about stuff in plain language.
Military ......................................................Sensible
Line Of Communication..(LOC).......................Road, railway, canal, whatever (and more precise)
Forward Edge of the Battle Area ..(FEBA)......Front line (the noisy bit)
Hostiles .........................................................The enemy, even if they're placid
Collateral .......................................................Ooops...............
Tactical Area Of Responsibility (TAOR) .........One invented by the clerical staff, this. As if war zones have a county line..
More, please....
