This is, I hope, the final version of the head gear in the TAG armor system. I've produced multiple perspectives showing the profile, the front, and the underside (pardon the sloppiness), which reveals several button locations and their functions.

Red - Infrared Vision

Green - Night Vision

Blue - Respirator/Air Filtration System

The other two designations are as follows:

Secure Point - where the mask locks onto the helmet's frame, thus negating the need for cumbersome straps. There is one on each side.

Release - this switch disengages the mask from the helmet for quick removal. There is one on each side as well.
