A Rifle Company has no organic vehicles but normally has 4 x HMMWV's (ammo, CO, 1st Sgt (supply), Utility(ambulance), plus others as needed/available/stolen)
Depending on mission a Rifle Company may have Engineer/AGL/HMG/AAV/Tank or other attachments

For all intents and purposes a USMC Rifle Company is an autonomous unit.
With the capability to call-in and direct mortars/artillery/helos/air support as required.
Most military services create companies for specific tasks (infantry/armor/air mobile). The USMC assigns tasks to companies. Everyone is trained, and practices infantry patrolling, mech assault, helo assault, and urban combat. At least once a year they spend a week or so doing rubber boats and amphibious assault. Every couple years they do a month or so of mountain warfare and cold weather/jungle/desert training; so about half of them at any given time know at least the basics, and senior people have done it often enough to be fairly proficient.

Other then when on patrol it's rare to see a fireteam/squad/platoon operating far from it's Company. But Companies often go days without anything but radio and resupply contact with their Battalion.
