You can't get the MACO Tactical or Omega Force Reaper since they don't seem to be in the game. The MACO Operational and Omega Force Harvester are for getting every elite optional in the STFs except for the ones from the Hive STFs, then doing the Tailor projects that are unlocked.

I'm really curious. Why ANOTHER constume that just isn't in the game?
