In '86 I was the LOOMIS Clerk for Airborne Maintenance Platoon. We received a young Lt as a Pl 2IC. At that time in the Z lines in Pet, there were parking spaces, assigned for senior appoints (IE - R Maint O, R Tpt O, etc). Well, somebody painted a sign which designated a parking spot for the new Lt - it was emblazoned "JAFO". We took to calling the Lt "JAFO", and he answered to it.
One day, he pulled me aside and asked what "JAFO" meant. Without missing a beat, I replied "Junior Airborne Forces Officer, Sir"! He seemed quite proud of that, and carried on with life.
I met him a few years later when he was a Major, he was now the OC of a Maint Coy in a Service Battalion (I'll leave the numerical designator out of it, just for fun). By that time, he was aware of what "JAFO" REALLY meant, but he had that same sign on his parking space.
How ya' doin' Dan - you still in??
(If you don't know what JAFO is - you won't find this funny - oh well).
