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 though without the shoulder, knee, and ankle armor of the higher ranks.

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, beacuse you could simply kill them by standing back and rapidly shooting the needler.

Combat against Minor Halo 3 Brutes
Much like the Halo 2 Brutes, they are the lowest in rank and therefore do not wield the far more dangerous weapons such as the Gravity Hammer. However, a Brute is dangerous nonetheless and with their new armor, they are far stronger. They most often use Plasma Rifles, Covenant Carbines, and Spikers. IN addition, they have a turquoise armor. One of the best ways to kill them is to use a Plasma Pistol on their armor followed with a Battle Rifle shot. On lower difficulties, to save ammo, you can melee them. However, use extreme caution when combatting Brutes in hand to hand combat as even Minors have the ability to kill obstinate players.

Trivia

 * Brute Minors are so much weaker than in Halo 2, a single Frag Grenade thrown underneath their feet will kill them.
