Flamers are armoured FND soldiers who charge with flamethrowers and set fire to wherever you hide. Their fuel tank is their weak point, so aim there or go for a takedown.
Flamers are rush units. They push straight at your cover and burn the area where they think you are, and they are reckless enough to hurt their own side.
Load armor-piercing rounds and aim at the fuel tank on the back. A takedown also works if you can get behind one. Keep your distance, because fire spreads through grass and cover fast.
The FND Fumigator is the weaker cousin and dies instantly when its tank is hit. The Special Forces Flamer is far tougher and attacks from range with an incendiary machine gun.
Corrupted Rakyat
Corrupted Rakyat are twisted, demonic copies of Rakyat warriors and the main enemies of the Vaas: Insanity DLC. They exist only inside Vaas's head, where his own people come for him.
FND Assaulter
Assaulters are the FND's standard riflemen, carrying AK-47s and frag grenades. You will fight them in almost every base and patrol, so learning to flush them out of cover pays off all game.
FND Engineer
FND Engineers rush you with sawed-off shotguns, throw EMP grenades and build auto-turrets to cover their squad. Kill them early, because their gadgets make the whole fight harder.
FND Fumigator
Fumigators spray PG-240, a poison that drains your health faster than fire and can also ignite. Their yellow back tank explodes when shot, so one good hit ends the threat.
