The '''M301 40mm Grenade Launcher''', also known as the "forty mike-mike" among troops, is a [[United Nations Space Command]] weapon designed to fire explosive [[grenade]]s. It can be [[Weapon attachment|attached]] to a number of weapons.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}

==Overview==
===Design details===
The M301 takes the form of an [[Wikipedia:Grenade launcher#Attached|underbarrel]] grenade launcher, which can be employed on a variety of firearms. The launcher commonly sees usage on the [[MA5B assault rifle|MA5B]] and [[MA5C assault rifle]]s fitted under the barrel, replacing the [[Flashlight|flashlight attachment]] standard to the [[MA5 series]].{{Ref/Site|Id=BNetMA5C|URL=http://halo.bungie.net/News/content.aspx?type=topnews&link=BAGAssaultRifle|Site=Bungie.net|Page=MA5C Assault Rifle|D=15|M=01|Y=2021}} The weapon is also employed on the [[M6634 flamethrower]] - the latter of which employs the launcher mounted above the firing nozzle of the flamethrower.{{Ref/Reuse|HWSG40}}{{Ref/Game|Id=HW1|HW|M6634 flamethrower in-game model}}

The M301 grenade launcher is capable of firing 40mm grenades at targets within a 99-foot (30 meters) zone, and up to 164 feet (50 meters) vertically—depending on wind, trajectory, and skill. The grenade launcher's rare tendency to detonate in the hands of unskilled operators has led to the M301 seeing limited use.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}

===Ammunition===
The M301 fires [[40mm grenade]]s. The launcher can be used to fire regular high-explosive munitions or [[Flashbang grenade|flashbangs]].{{Ref/Reuse|HWSG40}} This has earnt the launcher the nickname "forty mike-mike" among UNSC service personnel.{{Ref/Reuse|BNetMA5C}}

===Usage===
The launcher is employed in the [[UNSC Marine Corps]], in which it is commonly used in suppression, anti-armor, and anti-vehicle roles.{{Ref/Book|Id=Enc09|Enc09|Page=306}}{{Ref/Book|Id=Enc11|Enc11|Page=320}} The launcher is also used by the Marine Corps' [[Hellbringers]], who use the launcher mounted on their flamethrowers to fire [[flashbang grenade]]s - used to stun and surprise enemy troops.{{Ref/Book|Id=HWSG40|Halo Wars: Official Strategy Guide|Page=40}} 

The launcher's tendencies to rarely explode in the hands of unskilled operators saw it given limited usage, though it has seen increased use within the last hundred years.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}

==Operational history==
===Human-Covenant War===
The M301 was employed in [[2526]] during the [[Battle of Netherop]] and [[Operation: SILENT STORM]] by the [[SPARTAN-II program|SPARTAN-IIs]] of [[Blue Team|Blue]], [[Green Team|Green]] and [[Gold Team]]s.{{Ref/Novel|HSS|Chapter=3}}{{Ref/Novel|HSS|Chapter=15}}{{Ref/Novel|HSS|Chapter=20}} It was later used during [[2531]] by Hellbringer forces attached to {{UNSCShip|Spirit of Fire}} during the [[Harvest campaign]], [[Battle for Arcadia]] and [[Battle of Trove]].{{Ref/Reuse|HW1}}

===Post-war era===
The M301 continued to see service in the [[Post-Covenant War conflicts]], with Blue Team continuing to use the launcher underslung on the MA5C rifle in [[Operation: RETRIBUTION]].{{Ref/Novel|HRet|Chapter=14}}

==Gameplay==
===''Halo Wars''===
The M301 is useable in ''[[Halo Wars]]'', as an upgrade available for the [[Hellbringers|Hellbringer]] units. When unlocked, the grenade launcher allows Hellbringers to fire flashbang grenades as their Y-ability - stunning enemy infantry.

==Production notes==
{{Main|Cut Halo: Combat Evolved weapons#Assault rifle}}
During [[Development of Halo: Combat Evolved|early development]], ''[[Halo: Combat Evolved]]'' was to feature an underbarrel grenade launcher on the MA5B assault rifle. This grenade launcher survived through several iterations of the rifle's evolution, with the weapon at one point even sporting a secondary magazine forward of the main trigger to load grenades. At this time, the rifle's name given in the game HUD was '''MA-5 ICW/30mm CGL''' - possibly standing for something akin to ''Model A-5 Individual Combat Weapon/30mm Caseless Grenade Launcher''. This is in contrast to the M301's final 40mm sizing.

Ultimately, the grenade launcher was removed entirely, and only later referenced in a [[Bungie.net]] post about the MA5C rifle for ''[[Halo 3]]''.{{Ref/Reuse|BNetMA5C}} The weapon was first visually depicted in a [[McFarlane Toys]] figurine for the Hellbringer in ''Halo Wars'', which featured the launcher mounted atop the Hellbringers' distinctive flamethrowers.
