Does the Jimmy above the mess dress indicate you have a class 1 qualification in your trade? I thought it indicated your in the corps. Also a number of other Sgts in my unit have infantry qualifications that would have been worn above their stripes if wearing jumpers (e.g. Senior brecon, Signals Instructor, Mortar Section Commander etc), so when in (signals) mess kit should these be on mess kit?, if so is it above or on top of your stripes? I've also been told you can't wear cross flags on signals uniform, even if you earned it.
