5 Most Revolutionary Guns on Planet Earth
The field of military small arms is an underappreciated but important one. Although not as sexy as nuclear weapons, fighter jets or tanks, battle rifles, assault rifles, and machine guns have killed far more people and been involved in the forced transfer of more real estate than any other weapon—particularly in the so-called Third World.
Over the past eighty years, several military firearms have revolutionized infantry combat. Modern manufacturing techniques, combined with advances in polymers, metallurgy and metalworking technology, have created lightweight and accurate weapons. Likewise, visionaries such as Russia’s Mikhail Kalashnikov and America’s Eugene Stoner have produced innovative, reliable designs. Here are five weapons that made the battlefield as deadly as it is today.
World War II Germany was the first country to see value in a weapon smaller than a battle rifle that fired a lightweight cartridge at full auto. The German army, fighting masses of Soviet infantry on the Eastern Front, sought a weapon that could shoot faster from a larger magazine than the Karabiner 98k bolt action carbine, but fired a more powerful round farther than the MP-40 submachine gun.

The result was the MP44. Originally developed along the lines of a submachine gun, (the MP stood for maschinenpistole, or machine pistol), the MP44 fired 7.92x33 kurz from a thirty-round magazine. The MP44 could fire semi-automatic or fully automatic at rates of up to 600 rounds per minute. It had the appearance of a rifle with a large, curved magazine, shortened buttstock and pistol grip.
As the MP44 evolved, it became clear that it was not quite a carbine and not quite a submachine gun—but something entirely new. In 1944 it was designated Sturmgewehr-44, or StG 44. The StG 44 eventually became known as the first of an entirely new breed, the assault rifle.
The Soviet Army, aware of the StG-44’s existence, wanted an assault rifle of its own. Red Army Sgt. Mikhail Kalashnikov, a tanker wounded in the Battle of Bryansk, was fatefully diverted to the field of weapons design and came up a new assault rifle. His creation, like the StG44, used a lighter cartridge and a thirty-round magazine. The weapon was accepted into Soviet service in 1947 and became known as the Avtomat Kalashnikova 47, or AK-47.
The AK-47, although not the first assault rifle, was certainly the most influential. The AK-47 used the lighter 7.62x39mm round, which made the weapon more controllable when shooting in full auto. Unlike other fully automatic weapons of the time the AK-47 was simple to disassemble. It was made from stamped metal and other easily produced parts, so that countries with little manufacturing base—such as Albania, Cambodia and Sudan—could build their own copies. The AK-47’s simplicity and reliability helped terrorists and guerrillas operating in primitive conditions keep their weapons serviceable, and the AK has served prominently in most, if not all, wars of national liberation. Today the design soldiers on, with the Russian army fielding the newer AK-74M and, increasingly, the brand new AK-12.
The original M16 rifle was a wonder weapon that, once adopted for army use, quickly developed a reputation for being unreliable. It started off well enough: in 1956, Eugene Stoner patented a design for a direct impingement rifle that used gunpowder gasses to cycle the weapon. This simple design, the use of aluminum for the upper and lower receiver and plastic for the pistol grip and buttstock, resulted in a very lightweight weapon. The AR-15 had a maximum rate of fire of 750 round per minute and the 5.56mm bullet achieved muzzle velocities of up to 3,300 feet per second.
The new weapon, redesignated the M16, earned a reputation in Vietnam as being lighter and easier to carry than the older M14 rifle. From a logistical perspective, the same number of 5.56 rounds weighed substantially less than the 7.62mm rounds used by the M14. Unfortunately, a change in gunpowder and an unfounded belief that the weapon did not need cleaning caused many stoppages and problems on the battlefield. Nevertheless, once fixed the M16 became a highly effective assault rifle. Its pioneering use of plastics and aluminum has virtually assured that future weapons—particularly in the West—were correspondingly lighter and easier to handle. Today descendants of the original M16 like the M16A4 and M4A1 carbine are still in service with the U.S. Army and Marine Corps.
