From Halopedia, the Halo wiki
Hunters have very heavy armor that sheilds most of the body. It is equipted with a large sheild like hand and hand-held fuel rod. Hunters are dangerous enemys. They are mainly used for heavy defence and demolition. They work in pairs and can be a extremly big problem. The easiest way to kill a Hunter is to shoot the uncoverd orange part of the body on it's neck, stomach, sides, and back. It is also possible to melee attack this spot for the same fatality, though it it much harder. It is left open, however, when it tries to melee attack you and if you dodge it. It then staggeres for a short while, leaving you a short window of time to turn around and hit it's back. If you stand far from the Hunter it will use it's hand-held fuel rod to kill you. If you stand close it will try to smash you with it's powerful shield like hand. If you stand a little close to the Hunter it will charge at you and try to ram you with the sheild like hand. If you stand behind the Hunter it will lift the sheild like hand in the air then it will swing it back at you to try to crush you. All of these moves are fairly easy to dodge but will make a devastating blow to your health if you get hit. Grenades dont do much to the Hunter it will take quite a few to take 1 down. In Halo 2 when you first battle the Hunters the easiest way is to use the machine gun on the second floor of the building.
