Well Keith I would say this;
It is not the act of going on Ops and getting medals that you should be proud of, it is the fact that you made yourself available and ready to act when you got the calling. Territorial, reserve or Regular makes no difference to me buddy.
You should not feel ashamed when you march with your brothers and sisters on remembrance parades, you should be proud of the fact that you would have done what was required.
Medals or no medals, I would be proud to march next to anyone who was in your position. Oh and on a final point, your beret is the most important piece of kit your wear, it defines you, its your corps, your regiment and thats what matters mate.
