I always try to be helpful and provide factual information confirmed by many sources. You are welcome. Have a Happy Holiday Season Matt.
The 68th Battalion, 6th Armored Division wasn't overrun by any Panzer Divisions in any surprise attack despite what your countless google searches may show. They were only alerted on the 22nd and did "manage to have a wonderful holiday dinner" on Christmas. So I think they probably had time to white wash their tanks given that they weren't engaged until New Year's and were on the offensive. But thanks for sharing your very much incorrect thoughts, it's appreciated!
