The '''M7/Caseless Submachine Gun'''<ref name="H3">[http://www.bungie.net/projects/halo3/content.aspx?link=h3smg '''Bungie.net''': ''M7 / Caseless Submachine Gun'']</ref>, more simply known as the '''SMG''', is a [[United Nations Space Command]] infantry and special operations weapon. A suppressed version of the M7/Caseless Submachine Gun, known simply as the [[M7S Submachine Gun]], is also available for special operations.<ref name="H3R">[http://www.bungie.net/projects/odst/guide.aspx '''Bungie.net''': ''Halo 3: ODST Guide'']</ref>

[[File:Halo_3_SMG_view_enlongated.jpg|thumb|left|160px|The Halo 3 SMG.]]

The M7/Caseless Submachine Gun is an automatic UNSC 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 called the [[M7S 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 games, and has a maximum length of 62.7 cm (24.68 in.) when the stock is fully extended.<ref name="H3"/>

The SMG uses 5x23mm caseless ammunition, a radically different kind of ammunition than the kind found in other UNSC weapons. This ammunition is classified as "[[wikipedia:Caseless ammunition|caseless]]," 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.

This feature is very beneficial. In addition to increasing fire rate by removing the extraction and ejection phases of the weapon's cycle, it reduces friction inside the magazine, one of the main causes of jamming in weapons. This is also conducive to dual-wielding, since the user need not concern themselves with hot brass expelled from the weapon held in the left hand. The projectile itself is jacketed in metal (usually a copper alloy in standard military ammunition) to aid in penetration of the target. Caseless rounds are actually embedded into the block of propellant, reducing their length, allowing more ammunition to be stored in a smaller space.

The SMG's 5x23mm (.197 caliber) rounds, while smaller than most other SMGs, could classify it as a PDW (Personal Defense Weapon), which it has already taken several design forms.

Since it has a larger magazine than the [[MA5C Assault Rifle]], players will have to reload less often than if they were to use the MA5C. Because of the large magazine, one can easily continue through targets with little pause for reload. Like most UNSC firearms, the SMG is extremely deadly against unshielded targets, and can kill them rather quickly. In addition, the SMG serves as a better close range secondary weapon when already armed with a Battle Rifle. In combination with the Battle Rifle, the SMG makes a reliable close range support weapon when shotguns and swords are not available. The SMG serves better than the MA5C at close range due to its larger magazine and faster firing-rate, and is an excellent choice of replacement for the Assault Rifle in close combat situations, but not however at medium range.

The SMG can also form part of the most effective dual-wield combos in the game. The SMG, when dual-wielded with a [[Plasma Rifle]], can be a deadly combination because the [[Plasma Rifle]] depletes the opponents shields and the SMG's Armor piercing rounds do the rest. Another favored combo is dual-wielding the SMG with the [[Plasma Pistol]] Often referred to as the "[[noob combo]]". The charged shot from the Plasma Pistol will deplete the shield of your opponent and a full burst of SMG fire to tear through now-exposed flesh and armor. In ''[[Halo 3]]'', the SMG has been improved. By itself, the SMG can be an extremely devastating weapon in close-quarters combat, simply because of its high ammo capacity and lightning fast melee.

The SMG has 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 ranges the SMG is very powerful and is only outperformed by the [[Shotgun]], [[Energy Sword]] and [[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.

===Changes from Halo 2 to Halo 3===

*Red dots at the receiver end of the magazine.

*Slightly shorter foregrip.

*The sound of the weapon firing is slightly different.

 

The M7 appears to share its design from several real-world firearms; the [[wikipedia:Heckler & Koch G11|Heckler and Koch G11]], a caseless prototype assault rifle developed in the 1980's, the Fabrique Nationale de Herstal [[wikipedia:FN P90|P90]] and the [[Wikipedia:Heckler & Koch MP7|Heckler and Koch MP7]]. The M7 shares its caseless ammunition concept and feed mechanism from the G11, and its design from the latter two. As the MP7 and P90 are both personal defense weapons, it can be assumed that the M7 falls under this classification as well. Its slanted front, foregrip, collapsible stock, and possibly name come from the MP7, while its ergonomic grip and the horizontal magazine configuration come from the P90.

==Tactics==

===Campaign===

*The M7 SMG is always a devastating weapon when dual-wielded against [[Elite]]s and [[Brute]]s.

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

*Short controlled bursts with a single SMG is required to maintain ammo and effective range when engaging Covenant forces.

===Multiplayer===

*The M7 in ''[[Halo 2]]'' is not a sound tactical weapon to start off 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 has the option of taking player down with longer range weapons.

*Dual-wielding a M7 SMG with a plasma-based weaponry works extremely well against against shielded targets. Dual-wielding a M7 and an [[M6C]]/[[M6G]] might sound tactically useful, as it creates a deadly combo that can take out targets quick and efficiently. However, it requires a great deal of skill, and hand-eye coordination must be taken into account. The player should not consider it unless comfortable with it. The mixing of a full auto and a semi-auto weapon can be confusing and the chances of mistakes are greater.

*The M7 is a good choice as a suppression weapon because of the sheer volume of fire being produced if dual-wielded. The weapon's rate of fire can also be disorienting; when firing upon a [[Battle Rifle]] user or a [[Sniper Rifle]] user, their scope will become unusable once they are hit, reducing their accuracy and giving you the advantage and the incentive to charge assuming you are positioned close enough to your opponent.

*The SMG is a solid CQC weapon if there is no Shotgun or it has already been taken by other players. It is also [[Newbie|newb]] friendly, due to it having a large magazine capacity and being suitable for the "spray-and-pray" method. It will also give the player a chance for an easy kill since it will outlast all other weapons excluding the Assault Rifle and Machine Gun Turret in a one on one confrontation, and so can kill a player while they are reloading.

==UNSC Remarks==

*“The recoil isn’t bad but the M7 itself is relatively light. Not unpleasant to shoot, but a little tricky to control—it’s all about controlling the impulse.”

*“It’s actually comparable in weight to the [[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.”

*“Yes; I have fired it one-handed with the stock collapsed and the foregrip folded. No; I was not driving at the time, I was shotgun. Did I hit anything? Don’t know—probably never will—no more bogeys afterward, though.”

*“It’s not a death ray but nobody likes getting shot. Not even [[Brutes|Bravo Kilos]]. And you can fill the air with a lot of lead with an M7."

*John-117's signature weapon is normally the Assault Rifle, but in promotional art for ''[[Halo 2]]'', where that weapon is not available, the Chief is almost always depicted dual-wielding a pair of M7 SMGs.

*The SMG is, in many ways, the same as an [[MA5B]] Assault Rifle, as it has relatively similar range, power and capabilities. As with the MA5B, pulsing is a usable technique to increase accuracy and power. This may explain why it is a very common weapon in ''Halo 2'', as the MA5B Assault Rifle was in ''Halo: Combat Evolved''.

*In ''Halo 2'' when wielding one SMG, the stock is extended, and while dual-wielding the stocks are collapsed. In ''Halo 3'', the stock is always in one position in 3rd person view but collapsed in 1st person when dual wielding, but is still adjustable canonically.

*Although the M7 Submachine Gun is primarily issued to vehicle crews, it is also a favorite of commando teams in its sound suppressed version, the M7S.<ref name="H3R"/> The issuing of the M7 to vehicle crews is similar to how real world vehicle crews are issued carbines and SMGs because of the fact that these weapons would take up less space in a vehicle.

*In ''Halo Wars'', the Spartans in the cutscenes are using M7 SMGs that eject empty shell casings, despite the fact that the M7 fires caseless rounds. Also, in the ''[[Halo Legends]]'' episode "[[The Babysitter]]", the [[M7S/Caseless Submachine Gun|M7S]] can be seen ejecting shell casings. This means that there could be an older version of the M7 that uses traditional cartridges, though it is more likely that these occurrences are just a dramatic interpretation to enhance the scenes.

*Although the SMG has an enormous amount of recoil, it would not be possible, as the 5mm round that it fires gives little to no recoil in real life.
