Guerilla

Guerilla. Looks similar to the grunt, but wears a safari-colored uniform. Different guerillas may carry different weapons. One variety wears a vision-enhancement visor (Elite Guerilla).

Troopers - Only appear very late in the game, they wear green and take about as much damage as a normal guard and have a similar amount of armor. They're armed with high end weapons like chainguns and rocket launchers almost exclusively.
