no tacticsa required whatsoever (well i say this but it seems a micarcle to get the moves to work sometimes :/)
ive just gotten the hard badge, the best thing i can reccomend is not learning just where places are, learning where they are in relation to parts where land meets sea. for example 'le mans-france' is pretty much at the point, where the two sticking out land bits on the top left meet if you were to draw lines from them towards the centre of france.
likewise knowing where hawaii, luxemborg, honolulu (small countries are) spot on is a major help as you can pretty much get highest points on them everytime (you dont even need to neccesary get a strike(i only got 2) getting withing a very small radius will net you 500 odd points))
my main 2 areas which i dislike: the price of things rising when you upgrade it, and the fact that every enemy that can shhot seems to be able to shhot far further then your men can :/
