Well i think 9 is harder than 10 i had to do 9 on easy and just build as many men and tanks as i could and keep my boats off the shore. on 10 you kept the 800 dollar boats away from shore to destroy turrents then use airplanes to attack other stuff. have a few tanks but mostly airplanes and the boats. It did stop making stuff on lvl 10 tho :(
