3 battalions to a Brigade or Regiment.
3 Brigades to a Division
2, or more Divisions to a Corps.

Cool! Thanks for the info. Can I question you a little more?

- where does a 'platoon' fit in?
- are there any other unit size designations used in the US armed forces?
- how many men exactly are in a company?
- what is an 'attachment', specifically?
- is there any consistent difference between a battalion and a squadron, or between a brigade and a regiment?

Depends on unit and mission. I was in a regiment that had 5 squadrons.
