January

 * January 13th: During a mission to Station Delphi to investigate a ruptured Shaw-Fujikawa Translight Engine, Kurt-051 experiences a thruster pack malfunction and is sent into interplanetary space. The Prowler UNSC Circumference and the Frigate UNSC Tannenberg start immediate rescue operations, however, after over 5 hours of searching, and nearby Covenant activity, Kurt-051 is labeled as MIA. In actuality he was picked up by Colonel James Ackerson and recruited to train his Spartan-IIIs.

February

 * The Third Battle of Harvest is won in space: Preston Cole's fleet engages the alien warships that have again returned to the Harvest colony. Six years after the planet was attacked, UNSC forces emerged victorious at great cost.

 * February 4th: Captain James Cutter of the UNSC Spirit of Fire makes an entry in his log, reflecting on the five years leading up to this point in the war against the Covenant.


 * Serina instructs that production of M41 LAAG weaponry cease on Harvest, Warthogs instead to be upgraded with the M68 Gauss Cannon. Not that it makes much difference as drivers continue to 'splatter' their Covenant enemies, much to the frustration of their maintenance teams.


 * Helena Roman is KIA against the Covenant. Captain Cutter sends a message to her family in regards to her death.


 * Anders receives some unexpected readings on an EM band and asks a Hornet squadron en route to Rally Point Baker to investigate. They end up sighting a battallion of Sangheili. Sergeant Forge is assigned to Quadrant 4 to investigate.
