I am not one to ask how to get better at a game.

I know usually it just takes practice. Failure only makes you better, even online.

But when it comes to RTS games how do you get better? I don't have a deep history of RTS games, I never played Starcraft 1 when it was in its prime back in the day or any other RTS. But when I do play them, i this case Supreme Commander 2 which I really like. I can't keep with all my units or manage them right.

So I guess the question is: How does one keep up with all their units in RTS games?
