It can be modified, similarly to the metal helmet, with the same types of material mods as other pieces of combat armor. The helmet does not utilize the lamp like the mining helmet. This model displays what is possibly a headlamp, attached to the left side above the brow line. The combat armor helmet is the corresponding armor piece to the combat armor set.
Combat armor provides no latent protection from radiation, though through an exclusive mod it can result in the highest radiation resistance available to conventional armor (at the sacrifice of some ballistic and energy protection). The combination of protection makes it generally a better choice than equivalently modded other armor types, although combat armor becomes available at slightly higher levels than the corresponding tiers of leather and metal armor. Combat armor offers roughly equal ballistic protection to metal armor and equal energy protection to leather armor. Combat armor is considered 'Tier 3' and becomes more common as one enters into the middle levels (15-35).
