S4/BRT/1/7

S4/BRT/1/7 is a UNSC Marine Corps unit.

Background
They fought on Earth in early 2553 during the Second Battle of Earth, in the Battle of Voi. Later, they fought during the Battle of Installation 00.

Speculation
It is possible the S stands for the company, Sierra. The 4 may be fourth platoon of S Co, or fourth battalion that the company is part of. BRT could stand for Brigade Recon Team, which would be the infantry element of a reinforced Marine regiment, or Marine expeditionary brigade. The 1/7 could either be 1st Battalion, 7th Marine Regiment, or 1st Regiment, 7th Division. This is simply conjecture and should not be taken as canon.

Trivia

 * It is first seen on the side of one of the unit's M12 LRV Warthog in the UNSC Base on the Tsavo Highway.
