Like a lot of people I was in more than one regiment. I started as a boy soldier in the Royal Armoured Corps JLR. then went to my Cavalry Regiment. When I was discharged. I went into my local TA regiment the Light Infantry. I was happy with my cavalry regimental badge and tie. But some clever bugger in the "club" said I should have the powder horn on my blazer. Actually I did on my lapel. OK is there an etiquette for regimental blazers, or should I just get velro stitched onto my breast pocket.
