Second Squad

Second Squad is a generic name for small UNSC military units during operations. The name was employed by several UNSC units during the Human-Covenant War.

Battle of the Silent Cartographer
During the Battle of the Silent Cartographer in the Halo Conflict on September 20, 2552, Sergeant Waller was in command of a Second Squad. Second Squad took part in the initial beach assault on the island, and held the beach while John-117 searched for the Cartographer. After John-117 gained access to the Cartographer facility, Second Squad fought off Covenant reinforcements, but they were eventually killed.

Outbreak at the Containment Facility
A Second Squad, led by Corporal Lovik, was part of the UNSC forces that went to a Flood containment facility, with Captain Jacob Keyes. The squad may have been part of Fire Team Charlie, which was led by Staff Sergeant Avery Johnson. While Keyes, Johnson, and a group of Marines descended into the facility, Second Squad were ambushed by the Flood elsewhere in the facility. Corporal Lovik attempted to warned Keyes and Johnson over radio, but the transmission was cut off. Any survivors from the squad likely joined the Marines that were eventually found by John-117, but all of the marines in the group succumbed to the Flood when they were fighting to reach the extraction point designated by Echo 419's pilot Captain Carol Rawley.

Battle of Mombasa
Gunnery Sergeant Marcus Stacker led a Second Squad, comprised of ODSTs Walpole, O'Brien, Butkus, and Fones, during the Battle of Mombasa. The squad was part of the forces sent by the to support John-117 in boarding the Covenant  Solemn Penance, which held its position over the Uplift Nature Reserve in New Mombasa. However, the Pelicans were shot down by a Scarab in Old Mombasa Sector 0-5. Second Squad's Pelican crashed on the Old Mombasa beach, from where the squad fought their way to the nearby Hotel Zanzibar. The hotel soon came under attack by the Covenant, but John-117 was able to intervene in time. The squad then helped the Spartan push back to the beach to clear a path to the City Center.

Recovering John-117
During the opening stages of the Battle of Kenya on November 17, 2552, after finding and recovering John-117, Johnson led a Second Squad to the landing zone where they were to be extracted by Echo 51 and another Pelican. However, the Pelicans were shot down by Type-26 Banshee fighters and Echo 051 crashed on a nearby cliff. Johnson and the survivors of Second Squad were then captured by a Jiralhanae Chieftain. They were held captive at A2 Hydroelectric Facility, where they were later rescued by John-117 and airlifted out by Kilo 023.

Attack on Crow's Nest
Following the Covenant assault on Crow's Nest on November 17, 2552, a Second Squad was stationed as a perimeter patrol for above ground vehicular hangars GG and HH. After the base's destruction, the squad was attacked by a group of Covenant. Another marine squad, led by John-117 and Sergeant Reynolds, repelled the Covenant forces with Warthogs and picked the remnants of the squad up to join them in their way to Voi.
