S4/BRT/1/7

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

Background
They fought on Earth in 2552 during the Second Battle of Earth, in the Battle of Voi.

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.
