Which term refers to the smallest fighting element in an Infantry Platoon?

The smallest fighting element in an Infantry Platoon is the fireteam. A fireteam typically consists of four soldiers and is designed to operate as a cohesive unit for executing tactical tasks. Each fireteam is usually composed of a team leader, a rifleman, an automatic rifleman, and a grenadier, allowing it to effectively engage and maneuver in combat situations.

In contrast, a squad is made up of two or more fireteams, thus comprising more soldiers and increasing its operational capability. The section is a larger unit that contains multiple squads, while a platoon consists of several sections. Understanding this structure is essential for executing tactics and ensuring effective command and control within an Infantry Platoon.
