In which order do the smallest to largest army units rank?

The correct sequence of army units from smallest to largest is Fire Team, Squad, Platoon, Company.

A fire team is typically composed of around four soldiers and represents the smallest unit. When fire teams come together, they form a squad, which usually consists of two to three fire teams, leading to a larger group of approximately eight to twelve soldiers. When multiple squads unite, they create a platoon, which generally includes three to four squads and can consist of around 30 to 40 soldiers. Finally, when platoons combine, they form a company, which can have up to several hundred personnel, typically consisting of three to five platoons.

Understanding this hierarchy is essential for grasping how units interact and how commands are structured in military operations, reinforcing the importance of each level in executing mission objectives.
