Mukeiras Radar.
JW411. I remember the Army had radar at Mukeiras and I had a look in the bunker at the display set up. I believe it was a mortar locating radar designed for locating incoming PDQ. A search shows the Army used Green Archer at this time so perhaps that was the kit. Someone out there may know more.
Mukeiras used to get a bit lively at times I seem to remember, the Yemeni border was very close.
