A couple of briefs points.
As per usual we are deployed in very small numbers. The techies on my unit do guard duties but in between shifts on the line. This is a flight safety hazard. Its not a case of sending more guys out to theatre, we dont have them.
The SH force are more lined with the army than the RAF these days and we seem to manage with their rules.
If your on guard its for a reason, do the job stop whinging. Some rules are trivial but you have to draw a line somewhere, keep the bloody bar open though!!
