The '''M7/Caseless Submachine Gun'''<ref name="H3"/> is a personal defense weapon developed and manufactured by [[Misriah Armory]], commonly used by infantry, special forces, and vehicle crews of the [[United Nations Space Command|UNSC]] [[United Nations Space Command Defense Force|Defense Force]]. A suppressed version of the weapon, the [[M7S Caseless Submachine Gun]], is often issued to special operations personnel.<ref name="H3R">[http://www.bungie.net/projects/odst/guide.aspx '''Bungie.net''': ''Halo 3: ODST Guide'']</ref>

[[File:Halo3 M7 SMG left.png|thumb|left|160px|The M7 Caseless SMG as seen in ''Halo 3''.]]

The M7/Caseless Submachine Gun is an automatic submachine gun that fires from a 60-round magazine which is placed horizontally on the left side of the weapon. Due to the odd horizontal placement of the magazine on the weapon, it can be assumed that the magazine utilizes a circular ramp where the magazine meets the breech. This rotates the horizontally stacked rounds in the magazine 90 degrees until they align with the horizontal breech. An example of this can be seen in the present day [[wikipedia:FN_P90|Fabrique Nationale P90 SMG]].

The SMG has a polymer handle, folding fore-grip, [[iron sights]], and collapsible buttstock, as well as a titanium body. The SMG must be cocked before it can fire the first round. The charging handle is located on the right side of the gun and does not move during operation. Once the first round is fired, the gases from previous rounds force the breech to rotate and chamber a new round. Once the magazine is empty, the handle although not illustrated in-game, can either be pulled back and locked or it can be fully cycled after a fresh magazine has been housed. If it is first pulled back and locked, then it must be pushed forward in order to chamber a new round. The magazine release button is located between the red dots on the receiver and needs to be pressed before it can be flicked off. There is no ejection port due to the nature of the rounds fired.

The SMG has a rifled barrel that is 15 cm (5.9 in.) long.<ref name="H3"/> This weapon can also be affixed with a suppressor; in this configuration, the weapon is designated the [[M7S Caseless Submachine Gun]].<ref name="H3R"/> The weapon is 47.4 cm (18.66 in.) long with the stock retracted.<ref name="H3"/> The stock is always retracted in-game and has a maximum length of 62.7 cm (24.68 in.) when the stock is fully extended.<ref name="H3"/>

Unlike most UNSC weapons, the M7 uses [[wikipedia:Caseless ammunition|caseless]] 5x23mm ammunition, meaning it does not have a metallic casing surrounding the powder and sealing the bullet, propellant, and primer together. Instead of using this casing, the round uses a combustible adhesive to seal these components together. Because the adhesive and propellant are both vaporized when fired, there is no need to eject spent casings. Though not featured in-game, contemporary caseless ammunition is highly susceptible to cook-off, the accidental firing of rounds due to built-up heat in the receiver.

Nicknamed the "bullet-hose", the SMG is one of the best close-quarters firearm due to its large 60-round magazine and hit-scan properties. Suited for close-range combat, the SMG is extremely deadly against unshielded targets and can down shielded targets within seconds if dual-wielded.

The SMG can also form part of the most effective dual-wield combos in the game. The SMG, when dual-wielded with a [[Type-25 Directed Energy Rifle|plasma rifle]], can be a deadly combination as the plasma rifle depletes the opponent's shields with ease and the SMG rapidly tears through their health. Similar deadly combination, often referred to as the "[[noob combo]]", is dual-wielding the SMG and [[Type-25 Directed Energy Pistol|plasma pistol]]. The charged shot from the plasma pistol will deplete the shield of the opponent and a full burst of SMG fire will tear through the now-exposed flesh and armor.

As aforementioned above, the SMG received the nickname "the Bullet-Hose" due to its high rate of fire, low accuracy, and inability to be fully controlled when fired in full-auto. The SMG's primary limiting factor is its poor accuracy, which limits its use to close range. At close-quarters combat, the SMG is only outperformed by the [[M90 Close Assault Weapon System|shotgun]], the [[Type-1 Energy Weapon/Sword|energy sword]], and the [[Type-2 Energy Weapon/Hammer|gravity hammer]]. Like most other human weapons, the SMG performs relatively poorly against shields, though this weakness is negated by wielding it in conjunction with a plasma rifle or plasma pistol. As stated before, the gun has recoil which causes the barrel to climb after continuous fire and will climb faster if players dual-wield it. This forces the players to continually move their reticule down to keep the enemy in their sights but is not a big limiting factor. This, as well as the poor accuracy can be slightly countered, using a burst-fire technique, unleashing about five bullets each pull of the trigger. It also has the problem of an extremely long reload time when dual-wielded, making it easy to be killed while changing magazines. This problem however can be solved by volley firing the weapons, so while one is reloading the other is still firing. This tactic reduces the power of having two SMGs but gives the advantage of approximately 40+ seconds of non-stop firing.

*Increased accuracy, range, damage and rate of fire

*The player's reserve ammunition capacity is reduced.

==Tactics==

===Campaign===

*The M7 SMG is always a devastating weapon when dual-wielded against [[Sangheili|Elites]] and [[Jiralhanae|Brutes]].

*Dual-wielding a M7 SMG with a plasma-based weaponry works extremely well against against shielded targets.

 

*In ''[[Halo 2]]'', the M7 is not a sound weapon to start with, but if no other option is available, minimize being killed by staying in a safe zone until a better weapon becomes available.

*If stuck with an M7, stay in close quarters, and do not venture out where an opponent can take the player down with longer-ranged weapons.

*Dual-wielding the M7 SMG with a plasma-based weapon such as the plasma rifle works very effectively against against shielded targets. Dual-wielding a M7 and a pistol can be tactically useful, as it can create a deadly combo that can take out targets quick and efficiently. However, it requires a great deal of skill and hand-eye coordination. The combination of a full-auto and a semi-auto weapon can be confusing and hard to handle when aiming at an opponent.

*The M7 is a good choice as a suppression weapon, because of the sheer volume of fire being produced if dual-wielded, especially when engaging a nearby [[BR55HB SR Battle Rifle|battle rifle]] or [[sniper rifle]].

*''“It’s actually comparable in weight to the [[M6 Series|M6]] — favorably, in fact. That and not having to worry about the hot casing dropping down on your boot makes it a pretty clear choice which one I think is the better system.”''

*In ''Halo 2'', when the player wields a single M7, the SMG's the stock is extended. when the M7 is dual-wielded, the stock is collapsed. In ''Halo 3'', the stock remains locked halfway in both the first-person and third-person animation, whether the weapon is being dual-wielded or not.

*In ''Halo Wars'' and ''The Babysitter'', the M7 SMGs used by [[Douglas-042]], [[Alice-130]], and [[Taylor H. Miles|Dutch]] eject shell casings. This is an artistic error as the M7 SMGs do not have any ejection ports to remove used casings, and that they are designed to handle caseless ammunition.<ref group="note">[http://forums.bungie.org/halo/archive32.pl?read=949702 When this discrepancy was brought up by forums user in ''halo.bungie.org''], [[Frank O'Connor|Frankie]] replied that there is a cased variant and that such variant is listed on the ''[[Halo Encyclopedia]]''. However, given that the M7 has a very small frame and that the cased ammunition would not be able to fit in the M7's magazine, it is unlikely that such variant exist.</ref>

Despite the M7 typically firing caseless rounds, there is a variant of the weapon that can be loaded with more traditional cased ammunition.<ref name="HBO">[http://forums.bungie.org/halo/archive32.pl?read=949702 '''halo.bungie.org''': ''M7 casings'']</ref>

*The ''[[Halo Encyclopedia]]'' states that, among its flaws, the M7 is prone to malfunctioning. This seems unlikely, as the weapon fires caseless ammunition, meaning no case is ejected from the gun, which is where most weapons malfunction. However, the caseless ammunition itself may be the source of some malfunctions. If a round does not fire, it is very painstaking to remove because of the lack of an ejection port. Also, the ammunition is prone to accidental firings if the air around it gets too hot, such as in cases where the gun overheats. Other mechanical aspects, such as the circular ramp that loads in the rounds are a possible area for a malfunction, as double-feeding or a misfire could occur quite easily in a mechanism like that.
