r.s,
Regarding your unfortunate experience with that particular breed of low life, I thought you may be interested to see how the UK military supports you and your colleagues and their particular methods of dealing with said troublemaker. Some are feasible, some not and some you would just only dream of doing. The thread is on the Army Rumour Service website (ARRSE) at:

Personally, I don't think you should tolerate any abuse from scum who don't know how to behave themselves and any excessive bad behaviour (your experience fits neatly into the category) should be greeted on the ground by gentlemen in black uniforms staring through the sights of a H&K MP5 (preferably with the safety off). Apologies? Ram them where the sun does not shine; they should have thought about that before they gob*ed off.
