What (army?) unit was this?

[cptsquid]

I worked in Kandahar Airfield recently (civilian contractor) and while I was there, there was a unit of the Army that I THINK arrived not too long after I did. They were wearing a shirt with what I THINK was the company or brigade or what have you logo (not sure what its called, might've been a motto) and I'm trying to track down what the heck that logo/motto said.
I know it was something like Hell's (?) (bombers? Angels? something). Sort of a devil on a bomb (I think... I know a lot of "thinks" in there. Blame it on early onset of senility but I cannot for the life of me remember the details. It was a rather overwhelming experience).

Does anyone know if there is a way to see what units were stationed in Kandahar (ideally with graphics for their logos)? This would've been Mar 08.

Any help would be greatly appreciated as this is really bugging me and I've not been able to narrow it down online.

Thanks!
