Spent a couple of weeks with 533 Jager, early 90s. In the event of a third unpleasantness, their plan was to drive east...A friend of mine recalls that as a young officer in BAOR in the 80s he was in a group chatting to a grizzled old German full colonel of tanks who had fought on the Eastern Front.
"M60, too big and slow. Chieftain, good defensive tank. Leopard, fast, agile and good on marshy ground."
"But there isn't much marshy ground in Germany."
"Not Germany. Bielorussia."
