How many men are traditionally found in a Marine rifle squad?

A Marine rifle squad traditionally consists of 13 Marines. This structure is crucial for efficient small-unit tactics and allows the squad to operate effectively in various combat situations. Each squad typically includes a squad leader, two fire teams, and an additional designated marksman or automatic rifleman, enhancing its versatility and firepower. The organization into 13 members balances the need for sufficient personnel for maneuvers while ensuring that leadership and command remain effective. Other options, such as 10, 12, or 15 men, do not align with the established structure of a Marine rifle squad, which has been designed through operational experience to be both practical and effective in the field.
