Seriously, I wish you guys all the best luck. Skillful oposition adds to this game a lot, milkruns are borring.
Just couple comments though. Remember, that successful mission and interesting one are not always the same thing. Keep the fun value high. Also, one mission by itself values nothing. Some fields you capture makes strat worse for you country, not better. Make a plan, every capture shall be a part of it. If nothing works, just smile, and try again. If not this day, then another. And, make it a rule for yourself, that every failed mission is your fail, every succesful one is a success of those who join. Give them credit, and blame only yourself. And, again, learn when mission fails.
I think there were good hints for mission planners by Ripsnort somewhere on these forums, you can search for them.
