Whilst not doubting pr00nes memory for one moment, the name 631 RSU (Radar Signals Unit) seems to ring a faint bell. In the 80's they lived on the ridge to the north of Gutersloh at Borgholzhausen (in an old Dutch Nike site). I went to visit them once or twice and sat in the radar vans as they played with German Tornado's over the Ruhr.
Edited to add - A quick look on LiveSearch shows the radar site on the hill amongst the trees to the west of Borgh. (looking a bit deserted now) and what looks like the storage area for the Nike's to the east of the village in a wood.
