Yes all of us with the problem all have the base game from the CM:BN 3.11 FULL installer (already patched up and sold as 3.11 on store), and cannot get certain US armor in the quick battle. When it is called upon by ai or human during a quick battle or clicking suggestions button for armor only battle, game crashes. Check out my us armor formations only list. There is a missing Howitzer group and some others  on the US armor only side. Axis seems to be fine.
