The '''M45 Tactical Shotgun''' (formally '''Tactical Shotgun, 8 Gauge, Pump Action, M45''') is a [[shotgun]] manufactured by [[Misriah Armory]].{{Ref/Reuse|EVG}}<ref name="Library">'''Halo: Combat Evolved Anniversary''': ''[[Library (feature)|Library]]''</ref> The M45 is commonly used by the [[United Nations Space Command]] alongside the [[M90 shotgun|M90 Close Assault Weapon System]], a functionally identical copy designed by [[Weapon System Technology]].{{Ref/Reuse|Library}}<ref name="stats">[http://halo.bungie.net/projects/reach/article.aspx?ucc=ordnance '''Bungie.net''' - ''Halo: Reach - Intel - Ordnance'']</ref>

== Overview ==
[[File:ReachSchematic - Shotgun.png|150px|thumb|left|A blueprint of the M45 Tactical Shotgun.]]
The M45 is used during most close-combat scenarios (particularly in urban areas with heavy enemy occupation), as well as in boarding actions.{{Ref/Reuse|EVG}}{{Ref/Reuse|Library}} It was used in numerous military operations in urban terrain (MOUT) situations during the [[Insurrection]] and was met with widespread acclaim by its users.{{Ref/Reuse|Library}} The M45 later saw widespread use during the [[Human-Covenant War]].{{Ref/Reuse|EVG}}

=== Design details ===
The M45 shotgun features a dual tubular, non-detachable magazine and is chambered for 8 gauge ammunition.{{Ref/Reuse|EVG}}{{Ref/Reuse|stats}} The base model and the M45D may be fed up to six shells whereas the ''E'' variant accepts twelve. It is a special-purpose weapon used in any situation where the range of engagement is limited and when over-penetration is not desirable, but maximum stopping power is required. Some variants of the M45 shotgun feature a [[smart-linking|smart-linked]] controllable choke.{{Ref/Reuse|universe}}

== Variants ==
=== M45D Tactical Shotgun ===
The differences between the M45 and the M45D are mostly cosmetic, as the M45D retains the standard six-round internal magazine and firing mechanism. The M45D is unexpectedly comfortable to fire and simple to control, despite the shotgun's powerful 8 gauge cartridge and light weight. This is due to the M45D's [[Wikipedia:Magnetorheological damper|magnetorheological recoil dampening system]], which is considered very under-appreciated. The M45D shotgun does not feature a [[smart-linking|smart-linked]] controllable choke, unlike some M45 variants.{{Ref/Reuse|bulle}}{{Ref/Reuse|universe}}

=== M45E Tactical Shotgun ===
The M45E boasts greater stopping power than the standard M45 and has a twelve-round internal magazine rather than the standard model's six-round magazine. It features blue iron sights instead of the red sights common to the original model, though it is otherwise superficially identical.{{Ref/Reuse|Anniversary}}{{Ref/Reuse|Library}}<ref name="DD6">'''[[Data Drop|Data Drop 6]]'''</ref>

=== Smart-scope model ===
Unlike past iterations of the M45, the smart-scope capable model is a dual-mode shotgun, capable of semi-automatic or pump-action operation.<ref name="H5G">'''[[Halo 5: Guardians]]'''</ref>{{Ref/Note|Id=Dual|While the in-game description of the M45 claims the shotgun is semi-automatic the firearm is always pump-action. However, [[Edward Buck]] appears to use the semi-automatic mode in the opening cutscene of the ''Halo 5: Guardians'' level "[[Osiris (level)|Osiris]]".}} It also features a [[Projection sight]].

==== Smart-scope variants ====
There are also several variants of this specific model:
* '''Lawgiver:''' This variant has increased stopping power, rate of fire, and accuracy compared to the standard smart-scope model.
* '''[[Blaze of Glory]]:''' This variant has the [[Kinetic bolts]] attachment equipped in order to fire hard-light projectiles with more range and added anti-materiél effect than the ''Lawgiver''. Its entire magazine can also be reloaded with one shell. In addition, its sound effect is the same as that of a [[Spartan abilities#Smart Scope/Hover|smart-scoped]] [[Z-250 lightrifle|LightRifle]] when fired in first person, and that of a hipfired LightRifle when fired in third person. The Blaze of Glory can also be found as a [[Special weapons (Halo 5: Guardians)|hidden weapon]] in the mission [[Blue Team (level)|Blue Team]].<ref name="H5G-BlueTeam">'''[[Halo 5: Guardians]]''', campaign level ''[[Blue Team (level)|Blue Team)]]''</ref>
* '''[[Oathsworn]]:''' ''Oathsworn'' is a series of custom M45 shotguns created by [[SPARTAN-II program|Spartan-II]] [[Kelly-087]].

== Derivatives ==
=== DTM Series ===
{{Main|DTM series}}
Due to the M45's popularity among UNSC service members during the Insurrection, [[Weapon System Technology]] opted to design a more affordable and more practical copy of the M45.{{Ref/Reuse|Library}} The resulting M90 Close Assault Weapon System is part of the DTM series, which is marketed to the military, [[WST DTM/Law Enforcement|law enforcement]], and civilians. The standard model of the M90 Close Assault Weapon System is functionally identical to the M45E,{{Ref/Reuse|DD6}} possessing a twelve-shell internal magazine, as well as matching the original in range, shot spread, and stopping power.{{Ref/Reuse|Anniversary}} The M90A is based on the original M45 Tactical Shotgun and performs almost identically, despite its longer barrel; it too features a six-round internal magazine.{{Ref/Reuse|EVG}} Although the M90 has since dominated both the military and private sector,{{Ref/Reuse|Library}} it is common for UNSC personnel (particularly [[UNSC Marine Corps|Marines]]) to use both weapons concurrently.{{Ref/Reuse|EVG}}{{Ref/Reuse|Library}}{{Ref/Reuse|DD6}}

== Gameplay ==
=== ''Halo: Reach'' ===
The M45 shotgun is more powerful than the M90A from ''[[Halo 3]]'' and ''[[Halo 3: ODST]]''. The pellets have a tighter grouping and the range is superior as well, which also makes it harder to hit multiple enemies at close range. Although this change is hardly noticeable, impact force can be noticed as damage is higher.

The shotgun is very powerful in small confined maps. It should be used as a "corridor sweeper" because of its extreme damage at close range. The ''Halo: Reach'' version also has more recoil than its ''Halo 3'' counterpart.

=== ''Halo: Combat Evolved Anniversary'' ===
In ''Halo: Combat Evolved Anniversary'', the M45E is used in lieu of the M90 CAWS featured in the original game.{{Ref/Reuse|Anniversary}} As the changes between the original weapon and its replacement are superficial, the weapon performs identically to the M90 in ''[[Halo: Combat Evolved]]''. The weapon model uses the M45 Tactical Shotgun seen in the ''[[Halo: Reach Beta]]''.

=== ''Halo 4'' ===
The M45D Shotgun, according to 343 Industries employee Chris King, has ''"a lot longer range now, less damage falloff, and is quite a bit more powerful than say the Reach version overall."'' In terms of relative firepower, the shotgun is a one-shot kill weapon and should be used for close encounters. It is notable for penetrating enemy shields, particularly [[Sangheili|Elites]], and it takes only two shots to kill a [[Promethean Knight]].{{Ref/Reuse|bulle}} 

=== ''Halo 5: Guardians'' ===
The M45 operates similarly to its ''Halo 4'' counterpart, with a few additions; like all weapons in ''[[Halo 5: Guardians]]'', it can be [[smart scope]]d to increase its accuracy (in this case, tightening its pellet spread with a trade off of increased recoil), its base range is increased, its magazine has been reduced to 5 rounds instead of 6, and its tactical flashlight (previously just an aesthetic part of the weapon's design) is continuously on. The shotgun still features the problem of pellet inconsistency, though, making it ineffective for engagements past {{convert|10|m|ft|sigfig=2|sp=us}}, where the similar but non-hitscan [[Z-180 Scattershot|Scattershot]] may be a better choice. The M45 is the preferred weapon of Kelly-087.

=== ''Halo: Spartan Assault'' and ''Halo: Spartan Strike'' ===
The M45D Shotgun has an extremely short range though significant spread; however, it inflicts massive damage at point-blank range, enough to kill an Elite Major in one shot. The weapon's ammo is capped at 30. Due to its extremely short range, it is not recommended to fight Brute Chieftains with this weapon.
==Non-canon and dubious canon appearances==
===Silver Timeline===
{{Notice/Silver|category=no}}
M45 Tactical Shotguns are used by [[Silver Team/Silver|Silver Team]] and other UNSC personnel in battles against the Covenant.{{Ref/Film|[[Halo: The Television Series]]}}

== Trivia ==
{{Linkbox|gameplay=yes|gallery=yes|gallerypage=Images of M45 Tactical Shotgun}}
* In the ''Halo: Reach'' [[Halo: Reach Multiplayer Beta|Multiplayer Beta]], the shotgun had cyan lights similar to those on the M90. The sights are red in the final game.
* In ''Halo: Reach'', the M45 is pumped at the end of every Spartan reload animation, whereas [[Sangheili]] cycle the action upon drawing the weapon. In reality, doing this with a loaded chamber would eject an unused shell.
* In the ''Halo: Reach'' strategy guide, the silhouette used to mark shotgun spawns points on multiplayer maps appears to be missing their stocks. However, the M45 does not feature a collapsible stock and does not appear in the final version of the game.
* In the second issue of ''Halo: Fall of Reach - Boot Camp'', the [[Unidentified captain (UNSC Dartmouth)|captain]] of the {{UNSCShip|Dartmouth}} retrieves several shotguns from a [[cryo chamber]]. In the first two panels, the shotguns appear to be M45s, though they appear to be M90s in subsequent panels.
