"had a few experiences on Hedgehogs using ZB, we found that the desert fox’s (no not Rommel !!) made the same noise as men. Had a few close shaves picking out camels ....and one night picked up a soaf patrol coming in from the Jebal ,down a wadi at Hedgehog Delta that nobody seemed to know about , might have saved a few turnips being shot off"
