Phoenix Logs/Banished Units/Grunts (Elite)
From Halopedia, the Halo wiki
Grunts commanded by an Elite
The Grunts in this squad are armed with plasma pistols, led by an Elite with a plasma rifle. Upgrades allow the unit to cloak themselves for a while and add an Elite second—in—command.
A Grunt's lot is not a happy one, but this squad has the advantage of being led by an Elite rather than a Brute, and whilst their average life-span is still short, it may be fractionally less unpleasant. The unit is relatively fast and effective against all enemy types and better at ranged combat than a Brute—led squad.
