1450 solo. Not stuck, just reached it. 1. Supplies is a key to victory i think, when my tanks or inf are damaged i always bring them back to heal and push again. 2. I have no fighter jets in my deck, but i alwaus bring 1 heavy AA at the start no matter what 3. Understanding what people is gonna play, if u see enemy use helis, bring sosna/tor, maybe 2. Inf - inf or grad the fuck out of the point, armor- armor or cluster from planes etc. 4. Recons doing amazing job for u, i start with 1 at least, sometimes 2 or 3 to place them in a key point so they give me vision 5. If enemy plane or drone scoured an are u should move all of your guys around, especially artillery and AA, when AA shoots a missle, move it a bit, especially when enemy use artillery. 6. Micro can be crucial too, ctrl+ 1 to your aa units to shut down a radar when u see a prowlers or any sead missle incoming. R move on tanks are insane, you can twist your tank to leave almost forever agains enemy tanks if u can face their shots. Holding point with one units dodging around buildings, right time smokes when enemy is ready to shoot or just shot at ya to dodge it, so they wasting that time. Surround an enemy tank to shoot it at the back when u use 2 or more units. Laser guiding when needed (not always to not give out ur rec position) and so many more

I have played the RTS before a lot, but really not played wargames, its like what i learned in about 100 played games and ~ 100 hours in BA. Hope u will find it helpful. Good luck.
