Hey guys, welcome to
TG!
To win your campaign, you're going to want to get ground troops moved up into the areas mentioned in the sticky. Ground troops are notoriously reluctant to move up. You may need to help them along by moving them manually.
While they're doing that, you can help out by running CAS and BAI missions against anything that might be in their way. Don't neglect the engineer battalions, they're the guys trying to fix the stuff you just made go boom. I'd also run OCA strikes against any remaining airbases where enemy fighter aircraft are based, with SEAD escort if necessary. Then I'd go for infrastructure targets like power, C&C and supply.
But your ground troops controlling the victory locations is what you're looking for. Sounds like you are well on the way to winning.
Let me extend an invitation to both of you to meet up with us on TeamSpeak and join in on some of our flights. No need to feel you have to wait until you develop more skills - we can help you along with that. I'm sure you'll fit right in.
