As I understand it, the problem with the Lossie party was that it was widely publicised on an open Facebook page; not in itself an issue except that the venue was 'outside the wire' rather than on airfield so limited control of entry would have been possible.
Despite the RAF SAR Force being on the periphery of the military (hence being dumped by MoD) that just makes a bunch of guys and girls in uniform a very easy target in these days of extremism.
Apparently the issue ruined the weekend of a 2-star (shouldn't have worked so hard at school)
but the decision to cancel the party was probably the correct one. As it happened, people who weren't under the command of the mil still went for a few beers anyway at the planned venue.
I suspect that any other planned events will be inside the wire to avoid similar censure.
As for 771 - brave boys and girls but why does the minor player in UKSAR always have the loudest voice??
