I am just about to begin making my second army, and I wanted it to be different than my Chaos army. My Chaos army is troop heavy with no vehicles, so for my marine army i want to do it with alot of vehicles, dreadnoughts, rhinos, bikes, etc. I dont want any marines to start out on the battlefield on foot. I was wandering if someone would give me afew ideas, and I also wanted to know how many Rhinos I should have to make an efective rhino rush.
