I like the idea of both full and half body versions . I suspect , as Pinky said , most of us will use them as generic crew, I will . Might an extra set of heads with headphones on , or sitting around the neck of at least the commander head be possible ? . No need for the loader as he didn't need them . Only 3 crew had them , commander and radio operator could both talk to and hear each other ( to pass on radio messages / orders ) , the driver could only hear directions from the commander , no mike to talk back . Think he had a click / light system to respond to commander , at least in early war tanks
