Just Another F-cking Observer: When humans used to take weather observations at airports, they had JAFOs that would run outside to check the weather and report it to the airlines and the air traffic controllers.

JAFO is an acronym associated within the Military, and is used as a derogatorily term and / or slang for new officers who join a Military Ship, Unit, or Squadron. - Just Another Fucking Officer.

We send Operational Demands (OpDem) to Command for more soldiers, and they send us a recently graduated Officer? What The Fuck? Why do we need more fucking JAFO's, they don't do shit, the troops hate them - Fuck, even I hate them!
