That bothersome wall came down. Germany wasn't reunified until 1990 though.
So next year we will celebrate 25 years of official unification.
The Bundeswehr inherited so many Soviet toys. Germany was the only NATO country flying Migs, and Mig-29s were later used as "Opposition Force" aircraft in NATO exercises until they were eventually given to Poland.
There are still Soviet Era tanks in Germany. Usually used for training in one way or the other. Sometimes they shoot them up. Tons of rusting wrecks on Tank and Anti-tank gunnery ranges. I've seen a T-72(?) and a BMP sitting around behind the wire of one base as well.
