Do I go quietly?

I'm going to retire after my forthcoming appointment to one of our government's ships has been completed. However I can't right a retirement letter, but instead, have to right a resignation letter. Considering my para-military outfit are a shower of politically correct, H&S nazis, can't run a piss up in a brewery, etc, what should I put in that missive?

Would, "I think that you are a shower of wankstains and I quit", be too strong?

Or, should I write, " I have had the honour to serve in the *** for more than 43 years, and it is with regret.................

Your obedient servant

PS. can I have an MBE.

Personally I don't care, but if anyone has any good lines for either, please let me know.

Note to self: Need to write the letter soon
