I was wondering when Wittmann would be brought up, the kill rings on this Tiger are purely for propaganda purposes no one would be mad enough to want to stand out on the battle field just think of a sniper in a high visibility jacket then you will get the idea, on other tanks and there are relatively few pictures showing kill rings they were mainly painted as thin as possible 10-20mm wide and more often painted black though you do see white and yellow, bright colours stand out also individual tanks with special or individual markings stand out this would encourage the enemy to target you first.

The interesting thing about kill rings is Wittmann never had them a few months after this picture was taken in Normandy and of all the other Aces there are only a small handful of pictures showing this tradition and none of the pictures are taken at the front always in a rear area during rest or repairs
