Slightly less tounge-in-chek-but-with-a-large-grain-of-truth... I think you're looking at either the M16 and such halftracks (so maybe not quite "armour") for actual AA vehicles or the M2 machineguns in AA mounts the regular tanks tended to have.
>>10208396Be very gentle with wiping it down, as it's in my experience easy to get it somewhat uneven between the bits you can get to and the bits you can't, and blending/redoing is hell and a half. Let it dry properly and wipe with a fully dry tissue/Q-tip/whatever.
