Elite Mercury Conqueror
From Destinypedia, the Destiny wiki
The Elite Mercury Conquerors are Centurions and Colossi who act as High-Value Targets, and patrol the Fields of Glass to neutralize any Vex and Mercury Defenders to maintain a foothold for the Mercury Theater for the Red Legion.
The Elite Mercury Conquerors behave like any High-Value Target does on any other world; patrol a certain area, neutralize any enemy they come across, and escape the area once their patrol is complete or are killed and drops a chest.
