Those lads dodging the bullets were hyped up on propaganda and patriotism, as well as being told from toddlerhood that "real men don't cry" that is show "womanly" emotioins. Thankfully, this emotional guilt trip has largely gone the way of the obligatory short back and sides and other repressive programming.
I did not see the TV programme to which you refer but can't imagine that the lads there were very much different to their predecessors in WWII.
A lot of lads died in the first twenty minutes of arriving on the Normandy beaches, and a overwhelming majority of the survivors have wept buckets over lost pals or just lost life since then.
Let's hope that the lessons of the waste of war will be learned and that such bloodshed can be avoided in the future. I doubt it somehow, it never stopped the folly of mankind in the past.
I'd much rather have a shed load of crying lads at a pop contest than see just one of them being shot to ribbons by an unseen assailant and to die face down in a salty puddle on the margin of a foriegn land, their life's blood ebbing unseen into the vast ocean; diluted forever.
