No thank you Mark. I recently acquired the R.P. Hunnicut book Firepower that covers all US heavies in great detail. I am not much for the vehicles that never were. These US heavies at least were built. I have always wanted to do icons for them for scenario builders here in the community after I saw your "Kitty Killers" thread years ago, I reposted it below. They will also be useful for Monty's Das Reich mod.
