I don't really see a problem with it, perhaps it could be laid out a little different, like have a major heading for Apollo, Thor, Paladin, etc, then under that heading have the weapon mount 20mm, 76mm, ATGM etc, so it's easy to see there are really only a couple of vehicles with different load outs..
I think perhaps the 20mm Apollo should be changed to a dual mount 76mm turret.. The Apollo is not fast enough to get in close with the 20mm..
