Need lessons

I have played a few matches, and lost pretty badly in all of them. I need help. I always play the British Isles map because I like it and its my home. Can anyone help me?
EDIT: I like playing this game even though I am really bad at it, if I can just get my tactics right I would enjoy it more and give other players a challenge.
