Back on the subject of what constitutes an 'enemy', about 30 years ago I was somewhat surprised to note that a certain Vulcan captain (an utter bell end) had self-authorised himself and his crew to 'Locate and photograph enemy shipping'.
In fact this was the Kiev, pottering about on the high seas. I happened to ask a passing Flt Cdr ('Paddington Bear') whether this was a private war between said idiot and the entire Sovietski Soyuz, or whether I'd missed something on the morning news.
'Paddington' went into low earth orbit, ripped up the auth sheet and rewrote it for 'MRR event'. And left a note saying "See me". Sound fellow.
Unfortunately when the crew got back, they submitted some photos to the MRR cell who went equally bananas when they worked out how many rules the idiots had broken when flying over an aircraft carrier at flying stations in international waters!
Shortly afterwards the captain found himself flying Jet Provosts with baby navs......
