Haha really funny article the pictures were fanatastic and clever.
One thing i noticed was that securing your helmet is actually a mistake. Soldiers dont do that they keep the straps open. The helemt is secured in non combat dress situations only. A helmet with the strap on can decapitate you if something explodes or hits the helmet near you. Strap on means head flies off with helemt strap off mean helmet flies off with head still attached :)
