Gray Team

Gray Team is the designation for a mysterious team of three SPARTANs of the UNSC Naval Special Warfare Group.

Background
Gray Team is the team that are noted to be "on battlefields too distant to be easily recalled" when the SPARTANS received the new MJOLNIR Mark V armor. The team was later identified to have been "on a mission far outside the confines of UNSC space, now missing for over a year".

Trivia

 * The Spartans' mission, location, and ultimate fate will be detailed in the new Halo novel, Halo: The Cole Protocol, which will be written by Tobias S. Buckell, author of "Crystal Rain" and "Ragamuffin". This was announced in an update on Bungie.net.
 * There are three Spartans in Gray Team, as shown in Fall of Reach, when Dr. Halsey says that "all of you are here, save three who are engaged on fields of combat too distant to be easily recalled."
