@BILLYREDNECK, ive patched this up now. Obelisks now have reduced health so should allow you to destory them all now no problems. Reinforcements issue seems sporadic when ive tested it. Will need to look into that again another time. Let me know how you get on fella.

BillyRedNeck thanks for the feedback mate. I will look to get this patched up. I had tested that and did manage to kill the obelisks. Did you use them individually?

The orcas aren't enough to kill the obelisks which is annoying. Frequently orcas get shot down on their way to the rally point and twice I heard 'reinforcements have arrived' but either nothing showed up or the chinook landed then flew off the map.

You can just about kill those obelisks with the 12 orcas, they dont get repaired so you can do one at a time if you want to save shots from the orcas

Yes but with 12 you can't kill all 4 obelisks. You have to attack it after the orca figth. I have parked the orkas near the last obelisk and attacked it with the tanks.

Wow 3 hours!! The SAM sites once destoryed will bring in an orca. there are 12 sam sites, kill all 12 and you get 12 orcas. Use the orcas once only salvo to take out the obeslisks then you should be good!

Hi now I have won the mission. Its very hard I needed 3 restarts to know how does the beginning with the Obelisk works. For me it tock 3h realtime to win the mission.
