7th Shock Troops Battalion

The 7th Shock Troops Battalion is a UNSC Marine Corps shock infantry battalion that served during the Human-Covenant War. It is subordinate to the 105th Shock Troops Division.

Reach
The 7th Battalion served during the Fall of Reach in summer 2552. By August 12, the battalion operated as part of a large joint task force that countered Covenant deployments in the Viery Territory, where it served in the northern region. Given the devastation caused during the invasion, the 7th Battalion likely sustained heavy losses of personnel and matériel.

Mombasa
On October 20, 2552, members of the 7th Battalion assigned to the frigate were deployed to the Kenyan city of Mombasa in an attempt to board the Solemn Penance. A D77-TC Pelican carrying part of this strike team was shot down by a Scarab assault platform in the city's older district, forcing the surviving occupants to take cover in the nearby Hotel Zanzibar. They were soon rescued by SPARTAN John-117 and assisted in the Spartan's destruction of the Scarab.

Installation 05
On November 2, after In Amber Clad arrived at Halo Installation 05 in pursuit of Regret's flagship, members of First Platoon of an unidentified company were deployed to the surface of the installation to capture the Prophet. After securing a landing zone on a remote island, some of the remaining members of First Platoon escorted John-117 as the Spartan moved toward the Prophet's location. Though the Spartan successfully assassinated the Prophet of Regret, the ODSTs were killed en route to the target.

Over the next two days, most of In Amber Clad's 7th Battalion contingent were killed by either the Covenant or the Flood. However, it is possible that some escaped back to Earth with the assistance of their newfound Sangheili allies, as did Commander Miranda Keyes and Sergeant Major Avery Johnson.

Trivia

 * The name of the battalion is an obvious reference to the number seven.
