Sorry, I really feel it was a remark in very poor taste that did not need to be made. My opinion, but I thought it trivialised the Remembrance Day silence that, now, as ever, should never be demeaned. In my mess, sensible, we had a saying, 'engage brain before starting tongue in motion.'. Black humour was abundant also; I suspect it is when people are dying around you, it's a mechanism for coping; however, some subjects were not considered suitable.
Making stupid jokes is always going to attract some flack. If you don't like it, don't do it. Fairly simple really...
