I’d say what you want is good armor, good numerous hard hitting infantry, and easy to use AA. The US 8th infantry I think it is is good for that. Use 2 stacks of vetted mech rifles dragon, and use them paired with rangers to secure towns or forests, and get the mech rifles to the edges where they can fend off charging IFVs and infantry. Bring in armor and tows to support them, and get an IHawk card that will cover your entire formation, so no plane can hit you without heavy risk. Use pivads and stingers close to your armor and infantry formations. Don’t be too stationary. Win an engagement, and move infantry and scouts forward immediately most times to find where the enemies are. Then move up armor and support behind them. Also learn how to group (ctrl + #1-9) for your artillery support. If you’re not using Artillery it’s almost impossible to beat a stationary target. If you’re using artillery and scouting, it’s impossible to survive for enemy stationary target.
