These infantry are stationed at forward posts and checkpoints where they maintain perimeter security at Helghast occupied territory. On the battlefield, they are equipped with the StA-52 Assault Rifle and occansionally the M327 Grenade Launcher. They are also trained in hand-to-hand combat techniques which they often show off to their enemies.
Officers are very common and appear throughout the Killzone campaign. Most squads of Helghast infantry are usually led by one or two officers. Officers behave similarly to regular Helghast infantry, although their armor is of slightly better quality and they can survive 1 or 2 more hits from most automatic weapons compared to standard infantry.
Killzone 2 & 3Edit
In Killzone 2 & 3 Officers are replaced by Shocktroopers, who are similar in appearance but have a completely different combat role. They share the same character model as the Medic in the Warzone online mode in Killzone 2 along with being armed with the StA-11 Submachine Gun.
