Been reading your posts the last few days and think you have been a cracking poster, with some insightful stuff, but the bit in bold is a little unfair to be honest.
Being for us to intervene is a big difference to saying I would go and across and fight, its super easy to say it on a message board, the poster was honest to admit he would be scared and wouldn't want to fight, doesn't make him a coward, just makes him normal, I think most squaddies get scared, just the training kicks it and as you will know from serving, when the shit hits the fan, your not fighting for queen or country, your fighting at that moment for your mates around you and that trumps being scared.
All my mates, some of my family served, i got knocked back but signed up for the TA ( medical less stringent in the TA it seems ) So i cant talk from real experience as never really served, but I know from my talks with my mates who did serve in warzones some of the thought processes, mind they were all different when they came back and didn't really like talking to me a civ as opposed to talking amongst people who really knew, as they had been there.
