Battle group

A Battle Group is a UNSC designation for a force of ships that is smaller than a Fleet. A Battle Group is roughly equivalent to a Covenant Task Force in terms of number of ships; however, a Task Force is far superior to a Battle group in terms of sheer firepower and technology.

A Battle Group is usually commanded by an Admiral, though there have been instances of smaller Battle Groups being led by Captains. Each Battle Group is assigned a number, or, when the number is not known, the Battle Group is referred to simply by its flagship. Battle Groups are also created on a temporary basis, with a specific mission or to accomplish a specific task.

Trivia
