The Armed Forces, both active and retired, are historically given more respect and unsolicited bonuses in the United States than in this country. It is most unlikely to happen in this country that discounts would be offered on the basis that one once served or are currently serving in the military or the police and almost certainly American companies have never even thought of widening the offer to other countries for obvious reasons. ...

I would be most surprised. There are so few British cruise lines. SAGA, Fred. Olsen Cruise lines (Norwegian owned but cruise subsidiary registered in the UK)? If you find that some line gives such a discount please share the information.
Carnival was suggested as one company who offered both active and retired military perosnnel discounts, but they are American but own Cunard which was British !!
