Heh.. Most of our tanks had no markings other than a bumper number. Quite literally, my 3 tank had 'B13' on the front, and on the back and nothing else but half the time it was covered with mud.
We didn't even have enough time to put our names on the things. I got the tank name on my tube by month 2, by about 2/3 into the tour the 3 tank had a name on its one, but that was it. 2 and four tanks had no names at all, though the platoon insignia eventually found its way onto the 3 and 4 tanks.
We maintained the markings that we inherited when we picked up our tanks, changing only bumper or unit numbers, fortunately the two tanks that had platoon markings happened to both have an upwards-facing arrow.
