The Light class type is known for it high mobility and low amounts of health. Each unit in this class type has a very specific roles that they must fill. From espionage (Infiltrator) to sniping (Sentinel) to capping (Pathfinder), these units are the best at their roles. Since they are highly specialized, these classes are not the best at wandering around and deathmatching other classes.
Classified as light armor, Peltast offers the least resistance to weapon fire but gives the wearer almost unrestricted mobility and freedom of motion. The armor jets on this armor allow the wearer to traverse large distances in a single burst.Sierra Entertainment (1998). Starsiege: Tribes Manual.
