Speaking from experience here. I’ve been unfortunate to have been involved in two major conflicts. I’ve seen and heard some nasty stuff.
My experience as part of ground-air Ops in Gorazde in Bosnia made me question everything and ultimately led to me quitting military service.
War changes people, it lets loose the demons inside people and without proper control can quickly and easily get out of control. Some of things I saw in Bosnia I won’t repeat on this forum. But it is what it is…War is the fkin pits.
If it comes to war then decency and humanity are the first victims, believe me.
There's soldiers on every side of the divide who enjoy (and enjoyed) their work too much; we're not talking about general military life, but rather destroying
things.
It's no different to the boys and girls who take pleasure from vandalising, breaking things and causing pain: too many soldiers take pleasure from destruction.
Wretchedly, this includes destroying people rather than material objects - taking lives. Murdering. When men (and now women) become desensitised, it's too easy.
They're not people at the end of the sights; they're enemies, mere objects to erase if required to do so and that's where the depravity comes from.
Like you say, combat and war is the pits, which is why it's compartmentalised.
