Military..?

Can someone please explain the system that the US Army uses as of how they organize Troops? (ie how many to a squad, how many in a company)|||army infantry= 4 in a team usually 3 joes and an NCO, 2-4 teams in a squad and 3 squads per company. depending on the unit it can have a headquarters and 2-3 companies or up to 6-7 companies to make up the battalion, again depending on the unit it can have 1-about 4 battalions to make up the brigade and 2-4 brigades making up the division. alot depends on the exact unit and what it does like infantry, field art., commo, etc. it all varies depending on what type of unit it is and what the job is. hope this helps!|||Check wikipedia|||Infantry- 8/9 to a squad, 4 squads to a platoon, 3 platoons plus a headquarters platoon to a company, 3 companies plus a headquarters company to a battalion, etc. etc.|||Gee I hope our enemy isn't reading this. While your at it 3 to 4 man fire teams per squad.
