The NHS can still work wonders for Veterans, particularly with "attributable" injuries. I've been to the Oswestry Orthopaedic Veterans Clinic a few times, as old crash injuries catch up with me due to anno domini.
Now have titanium shoulder joint; they couldn't do anything with my legs, but suggested I was up for a War Pension (well the crash was in a war). A few forms and examinations later, I find I am 20% disabled (not that I'd noticed) and so get a smallish tax-free pension, and the famous Vets Oystercard mentioned at Post 15 above.
Trouble is, I haven't got to London for a while.......
Interesting side fact. Talking to the PARA/RAMC half colonel who runs the Oswestry Vets Clinic, I asked why - it's still NHS after all - waiting lists were so short.
"Easy," says he "service people don't miss appointments without telling us!" Scarily, up 60% of NHS appointments are "no shows"..... which b%ggers up the lists.....
