Anyway, here's the breakdown:
Army: Infantry/armor/support thereof, limited sealift, and close air support (for themselves, usually).
Marine Corps: Infantry/armor/support thereof (designed for mobility rather than brute force), close air support, limited air-to-air capability.
Navy: Limited infantry/support (Seabees), massive sealift, at-sea combat capability, close air support, air-to-air capability, limited airlift, major nuclear capability, ballistic missile defense capability, major ground-to-air capability (Aegis).
Air Force: Very limited infantry/support, massive airlift, air-to-air capability (limited outside CONUS), secondary nuclear capability.
