Yep. I went home on 2 weeks R&R in June '04, (got married), and when I got back, my truck had been taken down into Kuwait and was up-armored. It now had 1/4" sheet steel on the doors and just below the cab. It wasn't much, but it made us feel a little better about smaller IEDs.
We started seeing some of the M915A3s with the full armor "capsule" in late '04/early '05. They had the ballistic glass and everything. They were Freightliners that would run about 65 mph. (Our 915A1s would top out at about 60, heavy). Anyway, the armored A3s worried me. If you got hit and crashed, if the cab twisted and the doors were bound, you weren't coming out. Pray you don't start burning. Eveything seemed to just catch on fire, too.
