;[[Weapons company#United States Marine Corps|Weapons company]]
A weapons company has in place of the three rifle platoons, an 81&nbsp;mm mortar platoon, an anti-armor platoon, and a heavy machine gun platoon.

;[[Headquarters and Service Company]]
*Headquarters Platoon consists of Marines from S-1, S-2, S-3, the Nuclear, Biological, Chemical Defense section, and the Chaplain section (one Navy chaplain and an enlisted religious program specialist).
*Communications Platoon, consisting of Radiomen, Wiremen, Techs, Data Marines, and the associated staff.
*Service Platoon, consisting of S-4, Motor Transportation, Food Service, armorers, and Supply.
*[[Scout Sniper Platoon]].
*Medical Platoon, which includes all of the Navy medical personnel for the rifle companies and the Battalion Aid Station (BAS). The allowance of 65 hospital corpsmen and two Medical Corps officers (doctors) is usually not completely staffed. As such, the BAS usually fields one doctor and 10–12 hospital corpsmen. The remaining personnel are assigned to the rifle companies, usually five hospital corpsmen per company.

;Tank and [[Light Armored Reconnaissance]] (LAR) companies
USMC tank and LAR companies are organized similarly to US Army tank and mechanized infantry companies, with the three line platoons consisting of four tanks or LAVs each, and the company command element containing two tanks or LAVs.

;[[Amphibious Assault Vehicle|Assault Amphibian Vehicle]] (AAV) companies
AAV companies have three platoons containing four sections of three AAVs each, for a total of 12 AAVs per platoon, and a headquarters section of three AAVs. The company also includes both command and recovery variants of the AAV, giving the company a grand total of approximately 42–45 AAVs.
