The Elite Minor, or blue Elite, is the weaker and more common version. This one is armed with a Carbine, the rough equivalent of the Battle Rifle, and probably more dangerous than Halo 1's standard weapon for the Elite Minor, which was a plasma rifle.
In Halo 1, Elites also sometimes used needlers and plasma grenades.
Elites have full body rechargeable shields that deflect energy and projectile weapons. Like the Jackal's armband shield, however, it can be completely drained by an alt-fire charge from the plasma pistol, leaving him open to damage from other weapons.
When an Elite's shields are drained, he will generally seek cover.
When his health becomes low, he will charge you in a suicide manuever.
When near you, they will usually attempt a melee attack.
Sangheili refers to all Elites, not just Minor ones.
