Operation: PHALANX was an operation of the United Nations Space Command on Circinius IV during the Human-Covenant War between 2531 and 2552. The operation saw the evacuation of civilians and observation of Covenant invasion patterns on the planet, utilizing intelligence gained from Operation: ABLE SENTRY's UNSC Marine force reconnaissance units. At least one Spartan-II—John-117—participated in the operation.^[1]

Trivia

While John-117 and Spartan-IIs helped surviving civilians evacuate, the Battle of Circinius IV resulted in the entire population, with the exception of Hestati squad, being annihilated.^[2] This creates a contradiction.
