Having just returned from Ops in Afghanistan I thought I would submit my offering for wider debate. Synopsis: I go to the TCU (ablution unit) that I have been using for the last 3 and a half months only to find that it has been designated âOfficers Onlyâ (sign on the door). Now I have my own opinion on this but that is not the question, I just wondered whether the wider Arrse community had an opinion on the matter one way or the other. I am interested if anyone can present a valid argument for the segregation of Officers / ORs ablution facilities on operations. Discuss.
