Why not?? I don't personally, but you earn the right to do it if you want to. It is something to be proud of, so don't slag them off for their service history and pride in their achievements. The US are proud of their ex-servicemen and women and people show it in public. This attitude stinks, should WW2 veterans stop wearing their medals in case people think they are showing off, or maybe ask the Chelsea pensioners to wear tracksuits.
