I just need to get some answers to a few questions
1. I tried the single player game with Takada and noticed I was attacking and the computer AI had 3K+ more troops than I did. I always had some points left over(7-20) depending on what units I picked. playing at the lowest difficulty setting I had to restart the first battle 4 times before I could win it. Is it normal to have that large a difference in troops? The second battle I just could not win and gave up. I know I don't have the hang of the combat system so I must be doing something wrong.

2.Is there anyplace where the keyboard key assignments are located in the manual?
3 Any good videos that show how the combat system works?
