The M2 Browning .50 caliber machine gun has touched the battlefields of every major American conflict since the Second World War.

Over the decades, the M2 — affectionately known among troops as “Ma Deuce” — has proved to be a highly versatile weapon. It has seen action while affixed to the wings of P-47 Thunderbolts during World War II, installed on riverine boats patrolling the Mekong Delta, and mounted atop Humvees cruising the embattled streets of Mogadishu, Baghdad, and Kabul.

Having first entered the United States military’s arsenal in the 1930s, the Ma Deuce remains to this day an extremely effective and widely used tool of war. But why is that so? How has the M2 Browning managed to outlast all other major American weapon systems? The simple answer: It’s a damn good machine gun.

Who Invented the M2 Browning?

John Moses Browning was one of the most prolific weapons inventors of the 19th and 20th centuries. Sometimes described as the “Thomas Edison of Guns,” Browning created some of the world’s most recognizable firearms, including the Model 1911 pistol, the Browning Automatic Rifle, and the M2 Browning.

Born into a Mormon family in Ogden, Utah Territory, in 1855, Browning discovered his passion for gunsmithing as a boy working in his father’s gun shop. By age 14, under his father’s tutelage, Browning had learned the fundamentals of manufacturing and engineering. The first gun he built was a slide rifle fashioned from spare parts that he gave to his brother as birthday present. His interest in the craft only grew from there.

Browning’s big break came in the spring of 1883, when he partnered with the Winchester Repeating Arms Co. Over the next several decades, Browning and Winchester collaborated to create a series of lever-action repeating rifles, pump-action shotguns, and semi-automatic pistols.

Browning’s work revolutionized the firearms industry and even the nature of warfare itself. In the 20th century, his patented designs became iconic rifles and machine guns. One example is the Colt-Browning Model 1895, or “Browning Peacemaker,” as it was called during the Spanish-American War. An air-cooled, belt-fed, gas-operated weapon, it was one of the first machine guns the US military carried into battle.

The weapon that made the most impact on the development of the M2 was the M1917 Browning heavy machine gun. The crew-served, belt-fed, water-cooled weapon system — which first used .30-06 ammunition — was ubiquitous in the trenches of Europe during World War I.

Why Was the M2 Browning Invented?

Gen. John J. “Blackjack” Pershing, while serving as commander of the American Expeditionary Forces on the Western Front during WWI, requested the development of a multipurpose heavy machine gun that could be used against ground troops, tanks, and aircraft.

The US Army Ordnance Corps relayed Pershing’s request to Browning with the stipulation that the gun he designed would shoot armor-piercing ammunition capable of traveling at 2,700 feet per second. Such ammunition didn’t exist at the time. Browning asked that the Army find someone else to develop the new ammo so he could focus solely on the actual gun. The Army agreed and contracted Winchester to develop .50-caliber cartridges.

Browning teamed up with Colt to build prototypes for the new machine gun using the M1917A1’s base design. The weapon would have water-cooled barrels, be fired from a closed bolt, and be recoil-operated, a signature Browning design feature. The prototypes were ready for testing on Nov. 11, 1918, the final day of World War I.

Browning’s creation entered service with the US Army in 1919. From there, the design continued to be modified and refined. After Browning died in 1926, Colt rectified certain flaws the company had identified in his design and in 1933 unveiled the M2 Browning machine gun.

In What Conflicts Has the M2 Browning Seen Action?

American troops have wielded the M2 in battle since at least the 1940s. The list of conflicts the machine gun has seen includes World War II, the Korean War, the Vietnam War, Operation Urgent Fury in Grenada, Operation Just Cause in Panama, the Gulf War, the Battle of Mogadishu, and the Global War on Terror.

In most, if not all, of those conflicts the M2 was used to great effect. On Dec. 7, 1941, for example, while Japanese planes strafed American battleships at Pearl Harbor, Messman 2nd Class Doris Miller defended the USS West Virginia with an M2 Browning machine gun. He held off the enemy with anti-aircraft fire long enough for his comrades to evacuate the ship. As a result of his actions, he became the first Black American service member to receive the Navy Cross.

The M2 also saw action in the air on that fateful day. Army Air Corps pilots 2nd Lt. George S. Welch and 2nd Lt. Kenneth Taylor raced into the sky with their Curtiss P-40 Tomahawk fighters armed with fixed Browning machine guns. The two pilots downed seven enemy aircraft during the battle.

In the Vietnam War, legendary Marine Corps sniper Carlos Hathcock killed an enemy soldier at a distance of 2,460 yards. The nearly mile-and-a-half-long shot was not from his rifle but an M2 Browning machine gun modified with a special rifle mount built by US Navy Seabees. The M2 also added extra firepower to helicopters, riverine patrol boats, and gun trucks during the war.

M2s were also prominent during the Battle of Mogadishu in 1993. The battle, portrayed in the book and film Black Hawk Down, saw Army Rangers and other US special operations forces using M2s mounted atop their vehicles to fight their way through the streets of Mogadishu. The machine guns’ .50-cal rounds smacked enemy fighters taking cover behind concrete walls, brick structures, and the doors of improvised fighting vehicles.
