The [[United States Marine Corps]] doctrine dictates that any active fireteam will include at least one 2-man [[machine gun|gunnery-team]] and summarizes its fireteam organization with the mnemonic "ready-team-fire-assist", the following being the arrangement of the fireteam when in a column:
* [[Rifleman]]: acts as a [[Reconnaissance|scout]] for the fireteam; "ready".
* [[Team leader]]: uses an M203 and works as the designated grenadier; "team".
* Designated automatic rifleman: uses an M249 light machine gun or [[M27 Infantry Automatic Rifle|M27 IAR]] and serves as second in command for the fireteam; "fire".
* Assistant automatic rifleman: standard rifleman tasked with providing spotting support, range-finding, carries extra [[light machine gun|LMG]] [[ammunition]], and offers close-protection should the fireteam fall under attack; "assist".
