I remember the live armed fiasco in the 80's at Brize, for some reason we were called to bolster the main gate, muskets were issued and then it was rumoured we were going to be live armed, so green cards were requested, ammo duly arrived and was being handed out and then removed again, muskets later on incidently were replaced with pick axe handles to be replaced with muskets again some time later..
Some poor Civi contractor turned up during all this farce and vehicles were thoroughly checked during the heightened alert, an air pistol was found in his boot ( left innocently in there by his lad apparently ) and he ended face down, palms up on a wet road in the rain, shivering with cold or fright and with a musket pointed to his head, while the Civi plods were called.. I hate to think what he said to his kid when he finally got home.
