An American battalion includes the battalion commander (Lieutenant Colonel-- in the Marine Corps, sometimes a Colonel), his staff, and headquarters, the Command Sergeant Major (CSM) (or Sergeant Major in the Marine Corps), and usually 3-5 companies, with a total of 300 to 1,200 soldiers or Marines.
I think the US scales down a level so they have a Captain running a company etc (they have more soldiers to command I guess)! The Company is commanded by a Major and in his company he has 3 Rifle Platoons of around 24 - 30 men each, commanded by a Lietuenant. The US still has 1st and 2nd Lieutenants, Australia did away with this years ago and only has 1st Lieutenants now.
