A desperately outdated steel army helmet without any additions. Provides no protection against anomalies or radiation, but can deflect bullets. This helmet was never particularly popular in the Zone, except for use in brief armed conflicts between factions. - In-game description.
It offers significantly more durability and protection from both gunfire and explosions compared to the gas mask, and can also be upgraded to use a mk. 1 night-vision module. Additionally, being made of metal gives the helmet an inherently high psy protection rating.
