Funny story (and true too):
When I was in the sand box our infantry unit was running an op with none other then 22SAS and Delta. Yeah yeah, call BS what ever. It was a large scale 'hit' that basically covered close to 15 some targets in Ramadi....all to go simul.
Obviously the SAS and Dboys took down the highest priorty targets. We rolled (along with Big Red 1 as armor suppport) to the other targets.
Anyhoo.....prior to the op a bunch of guys showed up to eat in our chow hall (which was nothing more then a tent with a buffet line of mermites). They were all scruffy and mish-mash looking.
As soon as I walked in I said really loud (not really meaning to be so loud and obnoxious) "Hey, who let Brown and Root in here?!" I was dead serious too though, they looked like B&R guys.
(ok, for those that don't know B&R were the civilian contractors that did just about everything over there as far construction jobs).
They all look up from there table for a second or two, shot me a look, then went back to eating. I had no idea who they were until later that night during the op. Anyway, it was pretty funny.
SAS lost a man that night. I had to make the notification to the SgtMajor of the unit. That was tough.
