Brevets and badges are earned and people are rightly proud of them. There is a time and a place for them to be on display.
My opinion;
CS 95 (normal daily work) - brevets, get 'em on. Obviously only applies to badges with credence hence I include my Mudguards!
CS 95 on ops - nothing, especially that stupid Royal Air Force thing.
Blues - currently no official badges provided. This is wrong. Brevets and old style Regt flashes get 'em supplied and on. I include shirts/blouses and jumpers in the term blues.
Try and take a Bootnecks dagger/flashes from him and there would be mayhem. We have worked hard to get our badges. I was AWARDED mine as no doubt aircrew are AWARDED theirs. I am proud and definately not scared to admit it.
So to answer the original question; allow us to be proud Sirs, that means get brevets on everything and ditch grobags for non-flying tours.
I eagerly await incoming pebble-monkey, empire-building, gate-guarding banter!!
