Editing Squad (section)

====United States Marine Corps====
In the [[United States Marine Corps]], a rifle squad is usually composed of three [[Fireteam#Marine Corps|fireteams]] of four Marines each and a squad leader who is typically a sergeant or corporal, Other types of USMC infantry squads include: machinegun (7.62 mm), heavy machinegun (12.7&nbsp;mm (.50 cal.) and 40 mm), LWCMS mortar (60 mm), 81 mm mortar, assault weapon (SMAW), antiarmor (Javelin missile), and anti-tank (TOW missile). These squads range from as few as three Marines (60 mm LWCM squad) to as many as eight (Javelin missile squad), depending upon the weapon system with which the squad is equipped. Squads are also used in reconnaissance, light armored reconnaissance (scout dismounts), combat engineer, law enforcement (i.e., military police), [[Marine Corps Security Force Regiment|Marine Security Force Regiment (MSFR), and Fleet Antiterrorism Security Team (FAST)]] companies. On 9 May 2018, it was announced that a USMC squad would be reduced to 12 Marines, with three fire teams of three Marines each with two new positions: an assistant squad leader and a squad systems operator. As of 2020, the structure has been changed to 15 men; assistant automatic riflemen are replaced with grenadiers and a new addition to Marine fireteams, anti mechanized infantry. All M16A4 rifles and M4A1 carbines are to be replaced with the M27 infantry automatic rifle. Depending on the mission, automatic rifleman may use the [[M249 light machine gun]] instead of the M27 IAR.<ref>{{Cite news|url=https://www.marines.mil/News/Press-Releases/Press-Release-Display/Article/1516580/marines-announce-changes-to-ground-combat-element-aimed-at-improving-lethality/|title=Marines announce changes to ground combat element aimed at improving lethality and agility |date=2018-05-09|work=marines.mil|access-date=2018-08-12|language=en-US}}</ref>
