Which Hat or Nae Hat?

[ctbuchanan]

I will be as sensitive as possible. My paternal grandfather served in the Yorkshire Regiment (The Green Howards) in WWI (he was the one at Ypres) and my Great-Uncle served in the Argyll and Sutherland Highlanders in the same war. My maternal grandfather was a surgeon and Major in the Royal Army Medical Corps during WWI. My father was acting Colonel in the Royal Horse Artillery at the end of WWII and my uncle disappeared on a Royal Navy minesweeper when it was sunk in the Aegean in WWII.

I'm very careful with any references I make to military service in the U.K. and am appreciative of the advise.
