A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design.

A section is a military sub-subunit. It usually consists of between 6 and 20 personnel. NATO and U.S. doctrine define a section as an organization "larger than a squad, but smaller than a platoon." As such, two or more sections usually make up an army platoon or an air force flight.
