Sir, with respect, you got it dirty, you clean it (IAW MT orders)
Just out of interest - who signed the orders (ie who is giving the order). Is it:
a. The MTO? If this is a junior officer, mod civilian or even a contractor and do they, therefore, have the authority to either issue an order to someone more senior or, in the case of the latter 2, issue and order.
b. The Stn Cdr? If it is then he/she would, most probably, be aircrew. So you can get this thing sorted out in the wonderful aircrew brotherhood (or sisterhood).
c. Anyone in the command chain in between a and b. In which case pick your own subsequent course of action.
Mind you, having picked up corpses and bits of corpses and loaded them onto the back of a lorry, I can't see what all the fuss is about. It's not the worst job in the world.
The worst job in the world is, of course,
collecting Winston Churchill's bogies
