question on the timeline of early mission

Game Informer said that the mission they played (one 1/3rd of it) takes place 8 months after Halo 4, before they are declared AWOL. This would take place a month after the events of Spartan Ops, and during the same time time as Escalation. I wonder how this is going to work in terms of the timeline, as Fireteam Osiris is sent after Blue Team after they are declared AWOL. Osiris going after Blue Team must take place after the Absolute Record arc, as from this pic, it’s clearly Tanaka. So how’s that going to work, if this early mission is before they’re named AWOL? In the game, it might be better explained, but so far this seems some what confusing. Also, how do you think this will tie into Hunt the Truth?
