I agree with MuppetoftheNorth.
The problem at night, when fuelled with drugs etc is they see a 'soldier' as an easy way to prove their manhood.
Sometimes they get it wrong
Friend of mine, ex-SAS (yes, really) faced up to one group. When this 68-yr old wasn't frightened, they legged it. Another little chap about 78 and all of 5ft 4 and 8 stone, floored a thug, 6ft and 16st plus.
What thug didn't know was that after war service in the RN Brookie was 'volunteered' to join the Army as surplus to RN requirements. He completed his re-training just in time for Arnhem.
Years later, Brookie was at Guernsey airport putting his baggage into a taxi. Voice bellowed out "Brookie, come here." Where upon the Governor, a Rear-Admiral no less, had the taxi driver put Brookie's luggage into the State car and then drove him to his hotel. The Governor then carried his luggage into the hotel. Style!
