The military and STRACOH
The military have always and will always play 'fast & loose' with the WTD, because those in authority know that if they adhered strictly to the regulations then unit establishments would have to increase - something that just isn't going to happen. So it's much easier to accept it in spirit, whilst ignoring what really happens on a day-to-day basis.
However, I have always understood (civil colleagues may wish to confirm this statement) that STRACOH is backed up by a full safety case, unlike any military system for planning ATC manning. Consequently, I think that if a military controller working a civil aircraft towards the end of a long shift had a nasty, a civil enquiry may well conclude that the individual should not have been on console. Who they would choose to blame is another question but, if past experience is anything to go by, no doubt the individual involved would attract most of the criticism.
The military ATC authorities are keen on safety cases backing up other decisions when it suits them, but have ignored STRACOH for far too long and it's high time the issue of military ATC manning and working hours was fully addressed and resolved - but I imagine heads will remain firmly buried in the sand in the hope that this problem will just go away.
