On the subject of SE winching, if the H&S mad UK military do it
Only occasionally, for one (overland) sortie, for one niche group of people. And that's not live winching - presumably last Brit Mil SE live winching would have been when the Whirlwind went out of service (assuming you don't count the odd Sea King which had an engine failure during winching!).
Please note I am not having a dig at those do SE winching - just clearing up an inaccurate statement.
