Red alert 3 uprising

What do the AI personalities stand for in skirmish mode? For ex. If I choose an allied opponent I get to choose between 3 different types of AI personalities, ambush division, mecha warfare, and fleet command. What the hell do those mean and further more why the hell wouldn't you give the description for each one so the player knows what they mean! Please Write Back Soon! I'm losing my patience with C&C and I have loved your games since I was 8 years old. Thank you.
