The recent riots in Northern Ireland over flags as well as the age old Rangers/Celtic rivalry intrigued me. Though it's probably no problem in the Royal Regiment of Scotland today, was there ever any issue with sectarianism in Scottish regiments? In terms of recruiting areas were there predominantly Protestant/Catholic battalions? Did this ever cause problems during tours of Northern Ireland? This isn't the NAAFI and this isn't a wah. It's a genuine question, so serious replies only please!
