Jiralhanae Minor

Brute Minors are the youngest and most inexperienced Brutes (Jiralhanae) of the Covenant.

Background
Minors in Halo 2 had little or no armor or helmets, though in Halo 3, the Minors have acquired a green with a lustrous blue-green hue Power Armor.

Combat against Minor Halo 2 Brutes
These Brutes have not yet earned the right to carry a Brute Shot, which makes confronting them somewhat easier than it is for their higher ranking counterparts. Since they do not have helmets, it is easy and best to use headshots from a Sniper Rifle, M6C Magnum, or a Beam Rifle.

They often make tactical errors such as standing in one place while firing, or rushing forward into enemy fire. They also fire in shorter bursts, and have somewhat less accuracy and lower rate of fire. They usually wield Covenant Carbines, or Brute Plasma Rifles. Still, it is foolish to underestimate a Brute of any rank.

Bungie Studios was not very happy on the outcomes of the Halo 2 Brutes. They said that they were only damage sponges and weren't as fun to kill as Bungie wanted them.

Combat against Minor Halo 3 Brutes
Much like the Halo 2 Brutes, they are not high in rank and therefore do not wield the far more dangerous weapons like the Gravity Hammer, but a Brute is dangerous nonetheless. And now with their new armor, they are far stronger. They most often use Plasma Rifles, Covenant Carbines, and Spikers. Also, they have a turquoise armor. Even though other ranks have the same armor shape, they are not of the same rank. One of the best ways to kill them is to use a Plasma Pistol on their armor, and then kill them with a Battle Rifle. On lower Difficulties, to save ammo, you can melee them, however, use extreme caution when combating Brutes Hand to Hand, even Minors.Or just spray with the MA5C then melee when armor is gone.
