With all due respect Hands_on123 he did not Complain to the military he drove at them. Had he in fact contacted them and complained and given his reasons (rearing birds) for not wanting low level helicopters near his property then I am sure that his property would have been marked on the relevant maps as out of bounds.
Whilst granted this would not have solved his immediate problem it would have offered a far greater long term solution and with less trouble for himself. A criminal conviction will no doubt now mean that he will loose his firearms/shotgun license's which as a gamekeeper are an essential tool. Also the various other effects of such a conviction.
Err, no. He would have got a very nice, long but clearly de-personalised letter that essentially says "we appreciate that you don't like us doing low level military flying, but tough ****. We're going to carry on anyway."
