Variant One of my helmet selection.
The Aegis. Features 4x IR vision on the Visual piece, placed so it can be moved up and down at ease. When closed, IR is displayed on three different screens. When open, HUD is used. Entirely closed in and has its own re-breather inside the helmet. Also includes double plating on the base and frontal part of helmet. A more "General Combat" design for this helmet.
Successor to the Aegis, the Guardian
Stealthier, sleeker variant, Variant Two, the Advantage
