I hope someone can answer my question. I have heard terms like Squadron, Brigade, Battalion, Company, Platoon, etc, but I don't know the organization or total numbers associated with each of them. Can some point to a web site that clearly shows (for example) an organization chart of how many battalions are in a Brigade? Does each branch of the military have different groups to identify them? For example, does a Regiment only exist in the Marine Corps? Thanks in advance for any help...I'm posting from work, so I might not be able to answer any responses.
