It's weird to sit back and look at this picture and imagine you were part of a world War or one of the other global conflicts. These weapons are tools of destruction and I'm sure many people, soldiers and otherwise didn't want to kill other people if they could avoid it. Bearing these arms meant you had to commit to doing something dreadful, that'll affect you for the rest of your life.
Then these people hold these weapons with smiles on their faces like they'd be excited about ending lives. Oblivious to the notion that many people sacrificed and killed so they can pose and smile in a peaceful house, free from the possibility of harm.
Again it's just weird.
