See Post #22, certainly matches the reports that I have seen from soldiers and commanders and discussions I have had with same. I think he is spot on, except for the comment on the ASV, and his unit didn't have any of those. ASV armor is insufficient, wasn't designed for the IED fight.
Also, be careful with pictures of burning HMMWV's, many of them burn after the crew has walked away unharmed. Ask BG Karl Horst.
We are sending Buffalos, RG31s, and Cougars into Iraq and Afghanistan as fast as they roll off the assembly line. Don't know if we can increase production by going to other manufacturers.
ASV's do worse than HMMWV's?
