Upcoming free DLC

Hey I watched the video about free DLC each month and I was thinking could you add the UNSC Hornet or Falcon please? Those Helicopters were best when it came to Big team death match and video making and I was wondering could you add this please
Also when are you adding Spartan Ops season two? Because I loved playing Spartan Ops and it was really fun to play with your friends and level up.
