Seriously, how many times does this have to be stated until it's something mentioned as a bug? We should be able to harm people while they're in the non-gunner positions on a tank.
Also, this is just slight nitpicking but, the appostrophe after the S for the names isn't how it should be. Only names that are religious based use an appostrophe after the S. All other names, though, have an appostrophe with an S, regardless of how the name is spelled.
