Hey Sarge, I recently completed a build of Italeri's M-109 kit, was pretty pleased with how it turned out (only a couple of minor fit issues with the running gear/tracks, otherwise an easy build). I know the kit allows it to be built as at least an A1 or A2, it might be able to be built as an A-nothing as well, as there are a bunch of extra parts on the sprues that are not called out in the instructions. You can check out my build over on the Modern Armor Group Build thread.
