Dennis,
Grunts would not know the difference between a D or H model but they would notice the difference if it were a B model because of the doors and the smaller cargo area and no side wells along the transmission. I have to believe that Bob found the right ship which was assigned to D/1/10th Cav. The records are the ones which are screwed up. Sometimes I spend half the night comparing reports trying to figure out which one is right. Most of the time it comes now to the best of five are two of the closest being the one I choose.
