Jiralhanae Minor

Brute Minors are the youngest and most inexperienced Brutes of the Covenant. Minors in Halo 2 had little or no armor, though in Halo 3, the Minors/Regulars have a complete armor set that is blue and, rarely, turquoise in color.

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 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 wasn't as fun to kill as Bungie wanted it.

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 Brute Shot or the Gravity Hammer, etc. But none the less, a Brute is a powerful foe regardless. And now with their new armor are far stronger. They most often use Plasma Rifles and Spikers. Also, brute minors have two types of armors, a turquoise armor and a blue armor. Also, some have a jump pack which is not as strong as Jump Pack brute's.

Other than this, little is known about Halo 3 Brutes.
