Jiralhanae Minor
From Halopedia, the Halo wiki
Brute Minors/Regular 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 turcouse in color.
Combat
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 or Beam Rifle to take them down.
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 an Brute of any rank.
