The Delta-Six Division is a cell of the Office of Naval Intelligence's Section Three. Delta-Six fields a small number of SPARTAN-IVs. The division deployed Spartan operators to eliminate key rebel leaders on Talitsa.[1]
Several MJOLNIR [GEN2] variants are used prominently by D6's Spartan operatives. Spartans deployed in lone-wolf operations favor the Ranger variant. The Taltisa mission saw the most prominent use of the Wetwork variant. Hunter-trackers are commonly issued the Stalker variant.[1]
