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 power.

A Battle Group is usually commanded by an Admiral, and each Battle group is assigned a number. 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.

Known Battle Groups

 * Sixth Battle Group
 * Battle Group Stalingrad
 * Sol Defense Group 3/A-5

Trivia

 * The funding the SPARTAN-II Program, including their MJOLNIR Armor and training, cost about as much as a Battle Group.
