Here are some shots of my work helmet;
CG634 Ballistic Helmet (Medium)
Issue cover (modded) (bought surplus, I have my original stashed if I have to do an exchange)
Surefire Helmet Light
ESS Profile NVG Goggles (Issue goggles, private purchase straps modded with velcro)
Everything here has some function, I drive an armoured vehicle so the helmet light comes in handy to check gauges and see controls in a dark cabin. The goggles are much better on the highway when driving compared to the issue ballistic glasses. A few IR tabs and a custom "EW" cateye on the back, and that's all she wrote.
