i think alot had to do with the crew as an example wittmann and his crew only really had the kill rings visisble on one of there tiger so4 the rest of there tigers never had them now that could be becuase of a couple of things. one being that once crews gained notority they had the ability to jump from vehicle to vehicle becuase they were considered the elite crews like wittmann did hence why it was so hard to find out what vehicle wittmann was in in villers bocage the second point being that kill rings stand out like a sore thumb through binoculars so a veheicle with a lot of kill rings is of course going to get a lot of attention from enemy gunners this was also thought the same by the german high command who passsed an order forbidding the practice of kill ring marking on vehicles operated by experienced crews. as usual this order was somtimes ignored and the practice continued through out the war and was usually at the discretion of the units. the practise was not often seen on tanks but alot of guns and spg continued the practice
