Operation KALEIDOSCOPE (Earth-5875)

Operation KALEIDOSCOPE were a series of classified assassination missions against high-ranking Insurrectionist leaders through the Secession, initiated by the UNSC at the beginning of the 26th century.

Operation
In 2502, with the growing threat of the Secession, the UNSC changed their approach in tactics to combat the many Insurrectionist groups. Instead of relocating exorbitant amounts of money and resources to combat the insurgents in large-scale operations, the UNSC emphasized assassination missions to be carried against important leaders or members of Insurrectionist groups. For the next five years, ORION supersoldiers assassinated many targeted leaders, including Jerald Mulkey Ander.

Ander was assassinated on March 13th, 2502 by then-Corporal Avery Johnson. Johnson and Nolan Byrne, serving as his spotter, acquired Mulkey's position in a fair distance, prompting to kill him with a M99 Stanchion rifle.
