103rd Shock Troops Battalion

The 103rd Shock Troops Battalion is an Orbital Drop Shock Trooper battalion of the UNSC Marine Corps.

History
During the Battle for Earth on October 20, 2552, elements of the 103rd Battalion of the 65th Shock Troops Division were assigned to the UNSC Navy's Fifth Fleet over Earth. When the Fleet of Sacred Consecration arrived at the planet,  deployed the ODSTs to infiltrate the fleet's flagship, Solemn Penance, over New Mombasa, though the assault carrier fled the planet while the battalion was dropping overhead of it, sending their drop pods into free-fall and killing most of the troopers.

At least one unit from the battalion, Alpha-Nine, went on to participate in the later stages of the Battle of Mombasa, the final engagements of the Human-Covenant War such as Operation: JOINT MONITOR, and the Draco III rebellion after the war. It is unknown what became of the battalion following these events.
