Indeed.
Before the eastern expansion I had noticed years ago how portions of Niedersachsen bordering East Germany had been designed as a huge tank trap (dams could be blown up to flood the plains), and the bridges and some other civilian infrastructure was dual use as well (e.g. signed/scaled for tank passage). Likewise I discovered in late 1989 that a lot of the non-local roads between villages in the DDR weren't really passable by passenger cars but would still have bridges able to support heavy armour.
It seemed like a deliberate policy of both NATO and the Warsaw Pact that if there was to be yet another large war in Europe it should start in Germany for a change.
