Why does the US Marine Corps use the M16A4 instead of the M4?

The accuracy and lethality of the M4 at long distances are not as good as those of the M16 series.

In modern warfare, the engagement distance is about 200 meters, so both M16 and M4 can be competent.

The M4 is short, so it is suitable for hand-to-hand combat, or more suitable for street combat than the M16 series. The accuracy and lethality of the M16 at long distances are better than those of the M4, so it is more suitable for use by conventional combat units.

In terms of power, the distance of 200 meters M4 and M16 have enough lethality, and beyond this distance M16 because of the relationship between the barrel and the barrel entanglement, the lethality and accuracy are better than that of M4.

In addition, the M16A4 cannot be considered old, the M4 series is not new, and the SCAR series is a relatively new model, but it is not large-scale installation, but a small amount of special forces. This includes the XM 8 series, which has been discontinued.

But it was only a matter of time before the M16, as well as the M4, were eliminated.

Every Marine is a rifleman".

This is a famous quote of the Marine Corps, and the standard equipment of the Marine Corps is now M16A4, with a barrel length of 510mm, which is 101mm longer than that of M4, which means that M16A4 can make the gunpowder burn more fully and the muzzle velocity is large enough when using the same bullet.

The Marine Corps in 02 was already planning to fully equip the M4, but in the second half of the year, it was announced that the M4 would be abandoned and the M16A4 would be refitted, that is to say, the original M16A2 was eliminated during this period, of course, the mechanized troops retained the use of M4.

In fact, the main reason for abandoning M4 is that the muzzle velocity of M4 is too low, resulting in a less traumatic effect than M16.

In order to effectively kill the target, the muzzle velocity of the U.S. military-standard gun ammunition M885 should reach at least 732M s. In this way, the bullet will begin to roll after flying a certain distance to achieve the lethal effect, and the M4 does not meet the requirements, not that the range is enough, and everything is OK.

As for what upstairs "the most combat-ready unit makes P90 or Thomson" is purely to sell cute, it is estimated that the game is played too much, P90 This kind of PDW Marine Corps If it is equipped as a standard **, then it means that they have given up 200m away from the killing, Thomson is the ...... of the US military standard submachine gun in World War III'm embarrassed

The Marine Corps is always the worst ** to fight the hardest battles Who let not have their own independent command and military expenses Military expenses and command belong to the Navy can be on the Marine Corps, which is always half a beat slower than other strains The Marine Corps is more likely to fight in the mountains of West Asia because of global deployment It is not wrong to use a longer gun like the M16 The M4 has a short barrel and is not enough damage Special Forces and Scouts still use the M4

There is unique gear, but few are state-of-the-art. When the Army's tanks were replaced by SEPs, the Marines were still using M60s, or M1s.

When the Army generally used M4A1, the Marine Corps mostly used M16A2, which could not be A4, and A4 was the Army's choice.

The Marines laugh at themselves and always use the most mature **.

Yes, but at that time, drug trafficking groups often used M4 or AK-47, containing, M4 has many types, easy to mix, like M4A1, M4A2, M4-R, etc., not to mention that M16A4 is powerful and has a long range, so M4 is rarely used, only those "vases" are used, only for appearance, there is no practical use, so that the troops of M16A4 are all combat-effective troops, and the most combat-effective troops are P90 or Thomson. Those guns were powerful and had a fast rate of fire.

These two guns are used alternately for better results.

Isn't it now that most of them are M16A2.

Haven't you heard of it? Ginger is still old and spicy! The fart is still old and smelly!

In the mid-1990s, the U.S. Army announced that it would use the M4 M4A1, reportedly to reduce the individual load when the Land Warrior system was introduced in the future. However, there is another rumor that the "Land Warrior" system will not be completed in the near future, in fact, some high-ranking people in the army have always been resentful that the M16A2 will be purchased from a foreign company, FNMI, and it happens that Colt has the exclusive patent rights for the M4 series, so they decided to buy a new gun from Colt.

Following the US Army's announcement of equipping the M4 M4A1, the US Marine Corps also announced that it will be fully equipped with the M4 M4A1 to replace the M16A2 originally used. In the second half of 2002, after some debate, the commander of the U.S. Marine Corps, General James Jones, officially announced through the Marine Corps Times that the U.S. Marine Corps, after two years of testing and evaluation, finally decided to abandon the full replacement of the M4 and equip the M16A4, and the equipment time began at the end of the year. But the Marine Corps also does not intend to fully equip the M16A4, and the mechanized units will still use the M4 as the main **.

Despite the fact that the M4 M4A1 was already accurate enough in the range of infantry combat, the Marines decided to choose the M16A4 with a longer range. Why would the Marines go back and re-opt for a 20-inch barrel? Some reports from Afghanistan seem to illustrate the choice of the Marines:

SS109 M885 shells showed a lack of lethality on the Afghan battlefield, especially when fired with M4 or C8 carbines. In order for the SS109 M885 to achieve effective killing, the warhead velocity when hitting the target must be more than 732M s. However, the M4 M4A1 has a low muzzle velocity and unsatisfactory traumatic effect, so some units have adopted heavier commercial competition warheads to improve the ballistic performance at the finish line, and some units have suggested the use of new bullets, which is mentioned in the article "Excerpts from the Survey Report on the Use of Infantry Equipment by the U.S. Army in Afghanistan".

However, the Marine Corps continued to rely on M16A2 as the main force** and did not urgently transport 31,000 M16A4s to Irazhong Wanggak until the start of the Iraq War in 2003. Due to the lack of numbers, mainly as SAM rifles, and the Army's 3rd Mechanized Infantry Division has long been fully reequipped with M16A4, it seems that the Army is also aware that the 14-inch barrel cannot fully replace the 20-inch barrel. However, the interesting thing is that this time the M16A4 is provided by two ** merchants, ** the army is Colt, and ** the Marine Corps is FNMI, it seems that the army is determined not to order standard rifles from FNMI.

There is also M16A4

The U.S. Army and Marine Corps have decided to replace the M16A1 with the M4A4, which has been in use for twenty or thirty years, for reasons that are not complicated. America's strategic goals have changed. After the Vietnam War, the United States lacked confidence in large-scale wars and devoted itself to small, rapid-response asymmetric special operations.

M4A1 came into being and has made great progress. After the end of the Cold War, the United States began to appreciate the international status of one superpower and many powers, and its war ambitions began to swell. In addition, the two wars in Iraq and Afghanistan made the U.S. military realize that the short-barreled M4A1 is still not strong in the face of open battlefields.

So the full-size M16A4 took to the stage. Although the M16A4 is similar to the AR family boss M16A2, it has been reborn, using the same flat-top receiver as the M4A1, a more complex RAS goggle rail system, unequal thick-walled barrels, etc., and an extended barrel gives full play to the firing energy of SS109 ammunition, with a longer range, a straight trajectory and a smaller muzzle flame. This is M16A4

This is M4A1

Colt RO777 M4A1 with fixed handlebar

Colt RO921** Type M4A1

Colt RO927 Early ** type M4A1

Colt RO977 M4A1 for Flat Top Receiver

The M4A1 is just a carbine, so it's not something different.

Sopmod is a ** system, not a gun. The rifle part of this system is the M4A1 with the replacement of the RIS handguard system

The same goes for Sopmod Block II, and the ** part of it is still a very ordinary M4A1

Any gun can be equipped with a grenade launcher and a handle, including an arquebus. The M4A1 is very convenient for loading a grenade launcher, as in the M16A1, the handguard can be removed and mounted on the tube, or it can be replaced with a handguard with a guide rail and mounted on the rail.

The RO777 with fixed handlebars cannot remove the handlebars, and can only be equipped with optical sights directly on the handlebars. The other three can be removed from the handle to change the sight, and of course the sight can also be installed directly on the handlebar.

In addition, if you need to raise the bar, there is also an M4A1 Sherman, which has quite a few models.
