Sometime after leaving the military, Sierra was tired of being lump on the log. She wanted to start getting back to the fox she was during her time in the Armor Corp. Though it would not be easy, fighting the memories of losing half her tank crew in a fire, getting shot in the shoulder twice in Epsilon Delta, then coming back to duty right after the Diamond Squad Incident where she lost one of her closest cousins, only to be demoted and discharged by a Zone Commander Drake. Though she did later have her rank reinstated, the damage was done, and she made friends with whiskey. Going through half a dozen jobs in about the same number of years, newly appointed Commander of Epsilon Delta, Striker reactivated all of Gen 1 Epsilon Delta he could, for reasons to be determined. For as much hell the military put her through, it was the only place she felt she fit in. Plus I need her to get ready because she's got some main character stuff to get ready for.
