These are some video's from a youtube user, which seem to show these armoured vehicles before being put on a train and driven away to be shredded/sold. The last muscle flexing of a once powerfull army I suppose.
This one is called "The last round", BMP being driven around at the trainyard.
This one is T-72 on the road, and shows what it says on the tin
Then 2 about T-55 and starting it:
Racing around, BMP, BTR
This one is called "Recovering scrap at Prora", and it shows them removing T-34 targets using a T-55 recovery variant.
This one is "Last day of the BMP-2 at Prora" and shows around the workshop and one of the few BMP-2's the NVA had.
This one is called "We also had something on wheels" and shows a BTR being driven hard
And the last is T-72 in Prora, shows T-72 being moved and the workshop.
Definatly worth watching them
