"I’ve seen a Spartan use two at once tearing the crap out of the little ones; sending the big ones down in bloody heaps. But I guess that’s what ya gotta be to pull it off: an action-movie hero or a seven-foot-tall walking tank..."

— Anonymous Marine

The M7/Caseless Submachine Gun, or more simply known as the SMG, is a United Nations Space Command infantry and special operations weapon.

There is also another silenced version, the M7S Submachine Gun, which is equipped with an external suppressor to mute gunshots and increase stealth. It is observed that many ODST and Special Operations units use this variant.

Introduction

The M7/Caseless Submachine Gun is a weapon seen in Halo 2 and Halo 3. At medium or long range, the M7 is inaccurate, but at close quarters, it is a flexible and reliable close-quarters weapon, and when dual wielded, SMGs are capable of causing extreme damage in a small amount of time. At close range, it has a faster and deadlier punch than the Assault Rifle. The SMG is considered one of the best dual weapons in Halo 2 and 3. With a high rate of fire, the weapon is extremely deadly up close, and even more so when dual-wielded with a similar weapon. The M7 also has a distinct, walk-up recoil motion if fired without pause. When dual-wielded with the plasma pistol (or any energy weapon), it can create a deadly combination. By charging up the plasma pistol to deplete the enemies' shields, the SMG can deliver the killing blow.

Summary

The M7/Caseless Submachine Gun (also known as the bullet hose or SMG) is a fully automatic, gas-operated, magazine fed, dual-wieldable, close to medium range weapon. The SMG fires 5x23mm Caseless FMJ (Full Metal Jacket) rounds from a 60-round magazine at a velocity of 427 m/sec (1300 ft/sec) with an extremely high rate of fire (15 rounds/sec or 900 rounds/min). This high rate of fire combined with the weapon's relatively low weight leads to tremendous recoil and forces the barrel to steadily creep upwards during continuous/ automatic fire. It also sports a telescoping stock and folding fore-grip. The SMG lacks range (only being effective up to 50 meters) as well as accuracy so it is strictly a short range weapon. If you carry this weapon you, ideally, should be good at short range combat (as close as you would be with a Shotgun). In Halo 2 only 15 shots would kill an opponent, given that they all hit. In Halo 3 we see an increase in damage, accuracy, and range.

Physical Description And Appearance

The M7/Caseless Submachine Gun is an automatic UNSC submachine gun, that fires 5x23mm Caseless FMJ (Full Metal Jacket) rounds. It 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 breach. 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 Fabrique Nationale P90 SMG, as well as the HK G11 experimental assault rifle, which utilized a vertical loading system and caseless rounds like the M7. It also has various points which it resembles the Heckler and Koch MP7, such as the name, foregrip, frame of the weapon, retracting stock, etc.

The SMG has a polymer handle, folding fore-grip, iron sights, and retractable stock, as well as a titanium body, and is gas-operated with a rotating breech. The SMG must be cocked before it can fire the first round. The handle to cock the weapon 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 mag 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. This weapon can also be attached with a silencer called the M7S (not in any Halo game), but causes an uproar silenced. The weapon is 47.4 cm (18.66 in.) long with the stock retracted (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. The stock is also fully adjustable. The Halo 3 SMG is basically the same but has a slightly shorter foregrip and has red dots at the receiver end of the magazine. This weapon doesn't possess a safety and is dual-wieldable.

Advantages

The SMG is an excellent suppressive weapon, in Campaign against an unwitting AI or at close range online. It is also works great against swarms of Flood. When firing upon a Battle Rifle user or a Sniper Rifle user, the scope will become unusable once the user is hit, reducing their accuracy and giving you the advantage and the incentive to charge assuming you are positioned close enough to your opponent.

Since it has more ammo than the MA5C Assault Rifle, you will have to reload less often than if you were to use the MA5C. Because of their large magazine, one can easily continue through targets with little pause for reload. Like other 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 (Halo 2 combo). In combination with the Battle Rifle, (the "BR" being used to target enemies at a medium to far range and the SMG being used as a secondary / close range weapon), 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. A lot of close-quarter players will wield SMGs in matchmaking to have a rapid, fast firing gun, so keep on the move at all times

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 in Halo 3, can be a deadly combination because the Plasma Rifle depletes the opponents shields and the SMG's armour piercing rounds do the rest. Another favored combo is dual-wielding the SMG with the Plasma Pistol (Often called "the noob combo" by bitter veterans and victorious masters, a title which is shared with the more prominent and common Battle Rifle/Plasma Pistol combo). The firing of a charged shot from the Plasma Pistol to completely deplete the shield of your opponent should be followed with a full burst of SMG fire to tear through now-exposed flesh and armor.

In Halo 3, this tactic has been made less effective when holding down the trigger of the Plasma Pistol as it will cause your battery to deplete rapidly. Other combination include, but are not limited to, Spikers, Maulers, dual SMGs, and the SMG/Magnum combos.

When dual wielded they become an extremely formidable close range weapon. An SMG/Spiker combo can be more effective than an SMG/Plasma Rifle combo, providing the player can cope with the recoil. The SMG is very effective against swarms of Drones at somewhat close range, but the Battle Rifle (when properly used) has shown to be much more effective against such swarms. The sub-machine gun has also been proven in combat to be a fearsome Close-Quarters Battle weapon, particularly against any unsuspecting foes caught off guard in a close range firefight. It is real effective in an infection game if you can keep firing long enough, though usually the Battle Rifle is more useful due to its accuracy.

An effective and intelligent tactic is to, instead of emptying both guns at once (which, whilst effective at very short range... is only really effective at very short range), alternate them by firing one at a time, then using the other whilst the first is reloading; this helps control recoil (as only one gun is generating recoil at a time) and ensures that you always have a loaded gun (note that on halo 2, due to its set up for the old controller, reloads BOTH at the same time when x is pressed [unless one gun is FULLY LOADED] so extra care must be taken to ensure that you don't end up with an enraged elite charging at you while you reload both guns because of your mistake...). As SMG ammunition is rare, don't rapidly fire as when the bullets are gone you will struggle to find any ammunition.

The SMG is surprisingly good against vehicles, both aerial and land.

Disadvantages

File:Halo3 Spartan-smg-01.jpg

Some players have nicknamed the SMG, "The Bullet-Hose", due to its high rate of fire, low accuracy, and uncontrollability. The SMG's primary limiting factor, is its poor accuracy, which limits its use to close range. At close ranges it is completely overpowered and outperformed by the Shotgun and Energy Sword. 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 you dual-wield it. This forces you to continually move your reticule down to keep the enemy in your 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, especially 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 SMG's but gives the advantage of approximately 40+ seconds of non-stop firing.

In Halo 3, the SMG has been much 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. Many players prefer a SMG to an Assault Rifle in close combat because of these traits. While the AR has better range and damage, the SMG is better in close quarters.

Against The Covenant

Employed against certain members of the Covenant, the SMG can be a useful weapon. When fired in short bursts, it can easily decimate whole squads of Grunts or Drones. The SMG is also very useful against Jackals, with the 5 mm round curiously "stunning" the Jackal. However, it is not as effective against Brutes or Hunters most of the time. The SMG also performs poorly against the energy shields of Elites. However, once the Elite is unshielded, it can be killed rather quickly. Against Elites, it is recommended to dual wield the SMG with a plasma weapon due to the latter's superior anti-shield capabilities.Yet if you are caught in a battle with an Elite and you only have one SMG, the best tactic is to melee then fire when the shields are down. This also works with Brutes in Halo 3.

Against The Flood

The SMG performs well against all Flood forms (except shielded Elite Combat Forms) due to the Flood's preference to close quarters combat. An SMG is capable of taking out large groups of Infection Forms. It is commonly used to shoot off a Combat Form's arms to prevent them from attacking you.

In Halo 3 the SMG rips through the Flood like paper, especially unarmored forms like the Human Combat form and the Infection Forms. It's not so good against the Tank Forms and other Pure Forms, due to their high resistance to all weaponry (except fire and plasma).

Ammunition

The SMG uses M443 Caseless rounds, a radically different kind of ammunition than the kind found in other UNSC weapons. This ammunition is classified as "caseless," meaning it does not have a metallic casing surround 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 chemical "casing" is vaporized when fired, there is no need to eject spent brass casings. Though not featured in-game, real caseless ammunition is highly susceptible to cook-off, the accidental firing of rounds due to built-up heat.

This feature is very beneficial. It reduces friction inside the magazine, one of the main causes of jamming in weapons. It also negates the need to expel casings, which also is a major cause of jamming, as mentioned above. This is important, as a user wielding two M7s at once would not want to have hot brass flying in his face from the eject port of the weapon in his left hand. The projectile itself is "jacketed," or coated, in metal (possibly copper or steel) 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 cues from (read below). However, these smaller rounds also mean that the round will tumble through flesh, instead of going right through it, like a larger round.

Influence

The M7 appears to take its design from three real-world firearms. The first is the Heckler and Koch G11, a caseless prototype assault rifle developed in the 1980's. The second is the Fabrique Nationale de Herstal P90. The last one is the H&K MP7. The M7 takes 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, extendable stock, and possibly name come form the MP7, while its ergonomic grip and the horizontal magazine in a bullpup configuration come from the P90.

Observations

Recoil from all but sustained fire is very controllable. 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. It could also be a favorite of ODSTs as it takes up little room inside the cramped HEV.

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 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 Bravo Kilos. And you can fill the air with a lot of lead with an M7."
• “The M7 is the wave of the future. Hopefully the Romeo Echo Mike Foxtrots will finally realize the benefits of caseless ammunition.”

Trivia

File:Silencedsmg.PNG

The M7S is a suppressed variant of the M7

• In the original Halo 2 trailer, the SMG's muzzle burst was red.
• A silenced SMG seems to be the default weapon for Halo 3: ODST's new protagonist, a Lance Corporal.
• The SMG was one of Halo 2's most popular weapons and a song about dual wielding them has been made. It is now extremely popular.
• After removing the Assault rifle from Halo: Combat Evolved for Halo 2, some found the SMG useful, and can even use it for distance combat. In Halo 3, however, most players favor the Assault Rifle for sheer power.
• It resembles the gun Austin uses on Dr Evil at the end of the first Austin Powers movie.
• The SMG is, in many ways, the same as an MA5B Assault Rifle, as it has relatively similar range, power and capabilities. This may explain why it is a very common weapon in Halo 2, as the Assault Rifle was in Halo: Combat Evolved. It might also be more popular with Marines than the MA5B, as it is more compact, allowing for closer action, and dual-wieldable, doubling its already awesome power.
• When firing the SMG continuously, the recoil can make it harder to aim because the SMG "climbs up" in continuous fire.
• The Level Outskirts has one of the biggest numbers of SMGs in any of the Halo games.
• In Halo 2 when wielding one SMG, the stock is extended, and while dual wielding the stocks are pushed in, and in Halo 3 the stock is always in one position, but is still adjustable canonically.
• Spare ammunition packs for the M7 SMG in Halo 2 are marked in red- the same as the MA5B Assault Rifle.
• It seems to be SPARTAN-117's weapon of choice in Halo 2, when dual-wielded, and he is frequently seen dual-wielding SMGs. This image is seen on the cover of Halo 2 and its strategy guide. Another possibility is that it's to showcase the then new ability to dual wield.
• 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. 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.
• While encountered throughout the campaign mode in Halo 2 , M7's are only usable in the levels Crow's Nest, Floodgate, Cortana, and Halo in Halo 3.
• They were first put into the games in Halo 2, but were seen before in the Halo Universe, like in Halo: Contact Harvest and Halo: First Strike and around the year 2535 in use by Kurt in Halo: Ghosts of Onyx.
• In Halo: Contact Harvest, Staff Sergeant's Avery Johnson and Nolan Byrne's squads use M7 submachine guns when they raid the insurrectionist bomb shop and again when they attack the Covenant on the Tiara. It was also used by the constables that guarded Governor Thune's office in Utgard.
• This weapon is used by many characters on Red vs Blue mostly on the Red Team. When Donut was once asked to fire (in Caboose's mind), he said he couldn't because it was a purse. Also, in a deleted scene in Season 4, it shows Grif actively trying to plug up his SMG to avoid combat by saying, "Oh Sarge, my weapon is jammed. Looks like I won't be able to fight."
• The SMG was originally going to be in Halo: Combat Evolved but was cut, possibly because the Assault Rifle made it obsolete without dual-wielding.
• The SMG originally was meant to have a transparent plastic magazine, where the user could see the ammunition feed into the weapon. It was found to not be practical, and was given a stamped steel magazine.
• The SMG in Halo 3 has a different firing sound than the ones in Halo 2. Also the Halo 3 SMGs are slightly more powerful.
• In Halo 3, the SMG will not fire immediately after meleeing. Instead, the firing sound will be heard for one second without the SMG firing anything at all.
• Despite all the physical augmentation that the Spartans have been through, they still take recoil from the gun.
• This gun can actually kill a Assault Rifle wielder. Fire a sustained burst, and then melee them. The rate of fire can take shields down faster than the Assault Rifle, and the melee will quickly incapacitate the opponent.
• This weapon's caliber (5x23mm) is seen engraved on the side.
• The name "M7" is most likely another 7 reference.
• The Doppler Effect makes for very interesting frequencies heard when shooting two SMGs at the same time; It can sound like a helicopter, a radio tuner, and a motorcycle engine when fired at different times.
• On the Halo 2 E3 Gameplay trailer, the SMG had a different reticle, similar to the one when dual wielding a Mauler with an SMG in Halo 3, and it was never reloaded.
• In the version of Halo 2 used for the Halo 2 E3 Gameplay trailer, the dual wielding system hadn't be perfected yet, so Bungie coded what looked like Dual SMGs, but really was considered one weapon in the system, so the player could switch weapons without dropping one.
• If you fire while changing to a Monitor, you will still hear the firing sound even though nothing is firing.
• The SMG seems to "take apart" (dismember) Flood faster than any other rifle (possibly due to the high rate of fire).
• The SMG is in some ways inferior to some of today's SMGs. The ones in the Halo games are lighter, fire caseless ammunition, and have large ammo magazine capacity for its size, but some of the modern day ones have lighter recoil, higher caliber shells, and are more accurate at range.
• It is likely the SMG is used by police forces and rebels due to it's compact size.
• The M7 greatly resembles the real-world weapon MP7, since both weapons are powerful and compact SMGs. The M7 name might just come from the MP7 name(removing the -P-) but still having Bungie keep the obvious 7 reference.
• Dual (or single) SMGs can actually be fired semi-continuously without having to account for recoil. Instead of simply holding the trigger, rapidly press it. This will fire the weapon(s) quickly, but the game will not consider it rapid fire and so will not implement the increasing recoil algorithm.
• The SMG essentialy replaced the Assault Rifle in Halo 2.
• One SMG costs 1484 cR to make.
• M7 is a reference to 7 since M=14th letter in alphabet which is 7+7 so M7=777
