Platoon organization within the U.S. Army and U.S. Marine Corps as of 2019 is as follows:

A tank [[platoon]] includes four Abrams MBTs organized into two [[Section (military unit)|sections]], with two tanks in each section. "A" section consists of the platoon leader (''platoon commander'' in USMC parlance) who is the commander of the vehicle designated as Tank 1, and the platoon leader's wingman, who is the commander of Tank 2. "B" section consists of the platoon sergeant, who is the tank commander of Tank 4, and Tank 3 is the platoon sergeant's wingman.{{sfn|ATP 3–20.15 Tank Platoon|2019|loc=1–2}}

The wingman concept requires that individual tanks orient off the tank to its left or right side. In the tank platoon, Tank 2 orients off the platoon leader's tank, while Tank 3 orients off the platoon sergeant's tank. The platoon sergeant orients off the platoon leader's tank.

The tank platoon is organic to Armor [[Company (United States Army)|companies]] of a [[combined arms]] [[Battalion (United States Army)|battalion]]. The platoon may be attached to a number of organizations, commonly a mechanized infantry company, to create company teams. It may also be placed under the control of an Infantry organization. The exact amount of control the gaining unit would have is determined by the command relationship established by its higher HQ.{{sfn|ATP 3–20.15 Tank Platoon|2019|loc=1–8}}

The Armor company is organized, equipped, and trained to fight pure or as a task organized company team. The Armor company includes an HQ and three tank platoons. The company headquarters is equipped with two MBTs, armored personnel carriers, and wheeled vehicles for mission command/command and control and sustainment.{{sfn|ATP 3–20.15 Tank Platoon|2019|loc=1–9}}
