No - they were gunners. It was a box on the back of a bedford where the gunners sat at a mass of kit. Didn't get a real look inside as the lads were secretive about what they were doing. I know its not Cymbeline or M-Star. maybe an early MAMBA? There was a big effort to track Serb radar emmissions as they were tracking IFOR aircraft from ZSUs and the like. We all thought it was part of that
I was with HALO Troop around that time in '96 based in Jajce, with other dets elsewhere. As far as I am aware we were the only Locating assets in theatre, although I stand to be corrected. We even got bounced up to the Yank area to try and solve a problem they were having, so Locating was a bit thin on the ground across theatre.
The cloggies were operating a big radar similar to COBRA, but it didn't look like that.
Bear in mind that around then, post Options for Change there were only two Locating Batteries left and we were taking it in turns to man HALO.
My guess would be scalies.
Could be Air Defence, not my area but don't immediately recognise the kit. There was some radar being trialled at the time, but that turned into COBRA, which didn't look like that.
An oppo of mine was on the COBRA trial and I'm pretty sure they didn't take it out to Bos that early. May be wrong though.
