Yes I know what it is. Group of battalions, recruited traditional from same geographic area. Each regiment has its little ways of doing things, history, uniform, etc. With all the mergers etc over the last 10+ years, some now only exist as at company level. I've a question. What functions does for example the Regimental HQ of the Royal Welsh perform, that could not be carried out by either of the battalions - 1 R WELSH (formerly The Royal Welch Fusiliers) or 2 R WELSH (The Royal Regiment Wales)?
