Hell(let loose)o, I know, that was awful... Anyway, I recently bought the game, I tried the training levels and I have absolutely NO idea what I'm doing. Can one of you lovely people give me a run down of how to play and what different symbols mean please? For example, on the United States practise mission there was a tall contraption with a symbol flying above it but I don't know how to interact with it at all.

OR, is there something in the game that will explain everything to me because there were no instructions or objectives on the practise missions. Any help would be massively appreciated as I really wanna get into the game, it looks so good and fun.
