I'm a Radio Operator in the 4-7 CAV. I am not a fan of the CAV, fwiw. Sorry all you tankers and scouts. :)
I requested MP when I re-enlisted,when I was told there were no slots, I requested Infantry. When I was told there were no slots, I requested to be inserted into an Infantry unit as a radio operator and go to Iraq.
Needless to say... I ended up as a radio operator in an Armor unit in Korea. Not pleased with that. And I bitch about it every chance I get ;)
I'm damn proud to defend my country though, and I'll eventually get home. So no worries.
The 1-506, 1-509, 1-503, 1-9 Inf and others were all just sent to Iraq. They had a one month long training exercise before I left, which the 4-7 CAV were the OPFOR(opposing forces or bad guys) for. I was setup in the 4-7 cav TOC. So I didn't get to play with the rubber AKs or put on the MOUT gear :(.
