Same here, I take it easy. No, real rush. I mean if you want a crappy base then that's all on y'all. Usually I start with,
Build a base, guard it till further instructions.
Upgrade your guns, economy it would also be a smart idea to upgrade your main troops so when the enemies come they can kill them more faster/easier.
Find where your enemies are at, watch their every move. Make sure you know their exact location.
Control the chokepoints if that seems to hard then just patrol/watch them.
If you control your chokepoints you can easily tell what your enemies are planning/doing.
Don't be scared to just send in a division.
Always help your teamates it will help you win.
When all of this is complete start ambushing your enemies to pieces. Don't be afraid!
At least that's what I do xD.
