Guardian Lance is a part of the In Their Defence series and focuses on ONI's Operation:GUARDIAN LANCE. The Outer Colonies have fallen. Russell-041, like the rest of the Spartan II's have slowly been falling back across human space, trying to stall the Covenant's unstoppable advance wherever possible. But now the Office of Naval Operations want him to go back out there. Teaming up with Doug-103 and Colin-142 the three spartan's will be sent back to Jericho VII to work out what the Covenant are doing on a world they should have glassed and prepare the way for a UNSC strike force arriving in system a week later.
