The US Marine Corps exercises, the M4 carbine is still strong, why can't the M27 completely replace the M4?

In 2009, H&K announced that it would develop a new weapon for the US Marine Corps. This is now the popular HK416 rifle, not only in the United States, but also in France, Norway, the Netherlands, and Portugal. Many western countries have purchased this weapon.

However, HK416 is the name given by H&K, and the internal name of the US military is different. The ACOG scope is called the M27 IAR rifle, and the Leupold high-magnification scope is called the M38 precision shooter rifle. The picture shows the actual combat exercise held by the US Marine Corps. This Ma Run is holding an M38 with an eight-fold lens.

Except for the scope, the M27 IAR and M38 are essentially not Too big differences are all high-precision weapons, which also reflects a major feature of the current US Marine Corps. They are very pursuit of long-range shooting accuracy, so even infantry can use M27 IAR rifles with an effective range of 800 meters.

The pursuit of long-range shooting accuracy is actually related to the war in Afghanistan and Iraq. Anti-American armed forces knew that they could not defeat the US military in a frontal war, so they secretly trained many snipers, trying to use long-range sniper killing to consume the active force of the US military.

The Marine Corps is directly under the command of the President and the Department of Defense, and has the highest degree of freedom in mobilization. It is also the main force of the US military in the Middle East. It is most threatened by anti-US armed snipers. This forces them to strengthen their long-range attack capabilities to eliminate them. The snipers who attacked.

Interestingly, the Marine Corps has not completely replaced the M27 IAR rifle and M38 precision shooter rifle, and some Ma Run still uses M4 carbine. Compared with the M27 IAR, the M4 is already an older weapon. Why should the Marine Corps equip it? There are two reasons for this.

First of all, the M4 still has operational value, because the Marines not only have to fight at long distances, but also have to consider town and street fighting, and the carbine is short and portable, and is more suitable for close combat.

Secondly, as a long-range weapon, the M27 IAR has not yet developed a matching grenade launcher. The US military still needs to use the M4 as the platform and use the M203 under-hanging grenade launcher.

In general, the trend of the Marine Corps to replace M27 IAR rifles is definitely unstoppable, but the M4 carbine still has its own unique role. In a short time, the M27 IAR cannot be taken. M4, so some Ma Run still uses old guns to ensure the maximum overall combat capability.
