Name a war, revolution, or revolt during the Cold War that involved the British Commonwealth, Western European nations or their allies and you've also named a conflict that had combatants fighting with the Fabrique Nationale FAL.
No wonder the FAL earned the nickname "the right arm of the free world" and became a symbol of the struggle against Communism.
In many ways, it was the West's answer to the Kalashnikov, albeit one chambered to fire the heavier 7.62 x 51 mm NATO round instead of the AK-47's 7.62 x 39 mm intermediate round.
Created in the years immediately after World War II, FN eventually produced 2 million FALs (Fusil Automatique Léger or "Light Automatic Rifle") that were used by the militaries of more than 90 nations.
At one time, the FAL was even the official battle rifle of most NATO-member countries. It was even considered for the role as the United States' main battle rifle.
Frankly, the FAL was everywhere. For example, consider the Six-Day War in 1967.
A common misconception is the 9mm Uzi was the weapon of choice for the Israeli Defense Forces. Actually, Israeli soldiers carried more FALs than Uzis when facing Egyptian, Jordanian and Syrian troops.
Then, there was the 1982 Falklands War. The Argentine Army carried the full-auto version of the FAL; British troops had the semi-auto L1A1 Self-Loading Rifle model of the FAL.
When captured Argentine troops piled their weapons, British infantry and Royal Marines often walked over to the stack and retrieved the full-auto FAL so they could spray more lead at the enemy.
In Argentina, thousands of FALs underwent armory rebuilds in 2010, a sure sign that nation will continue to put the weapon in the hands of its troops.
How the FAL saw the light of day is a story that combines the tactical realities that emerged out of World War II and the politics of who would lead who during the Cold War.
The success of the innovative Sturmgewehr 44 assault rifle convinced ordnance officers and weapons designers that era of the bolt-action battle rifle was dead and gone. Lighter cartridges in select-fire assault rifles captured the imagination of weapons designers.
Only the United States fielded a heavy caliber semi-auto battle rifle, the well-regarded M1 Garand .30-06 weapon that Gen. George S. Patton called "the greatest battle implement ever devised." But the future was one that fired full auto – and the Garand did not.
Caliber was also an issue. As weapons designers on both sides of the Atlantic toyed with prototype battle rifles the British tested a 7 mm (.280-caliber) round in the new FAL and liked it.
In the United States, the Army wanted to stick with the .30-caliber round, flatly stating that no other cartridge could hold its own on the battlefield.
With the formation of the new NATO alliance in 1949, generals and civilian planners both talked of the necessity to standardize equipment, weapons and supplies.
"The laudable aim was one that had been much in the minds of many forward-looking military thinkers for a long time," writes David Westwood, author of Rifles: An Illustrated History of their Impact. "For experience had shown that the United States and Britain often fought side by side, and commonality would be to the benefit of all including soldiers in the field."
One thing was certain: the British were impressed with the FAL and were willing to choose it over other weapons.
It was deemed the superior firearm to competitors because it was easy to maintain, field strip, and clean. It reassembled without special tools and it was a select-fire weapon – but it fired the lighter round.
The "gravel belly" U.S. generals would accept nothing but a .30-caliber weapon, insisting on the superiority of a prototype called the T25, a forerunner of the M14 that was nothing more than a glorified Garand.
Soon, there was a "Battle of the Bullets" that went as high as the White House and 10 Downing Street. Pres. Harry Truman and Prime Minister Winston Churchill even held a mini-summit, where rumor has it they struck a quid pro quo – the U.S. would adopt the FAL as its main battle rifle if Britain backed NATO adopting the 7.62 x 51 mm round.
NATO relented and adopted the round. However, the U.S. reneged, developed the M14, which fired the NATO 7.62 mm cartridge, and adopted it as the American military's main rifle.
In the end, it didn't matter to FN because NATO countries (including Britain) began snapping up the FAL chambered for the NATO round.
Many consider that combination of weapon and cartridge the quintessential pairing of battle-rifle and bullet during the 20th Century – the FAL went into production in 1953 and FN continued to produce the rifle until 1988. The M-14 fell by the wayside as the main U.S. battle rifle within a few years, replaced by the M-16.
"Regardless of the political activity that went on before its adoption, the 7.62 x 51 mm NATO turned out to be an excellent, powerful military cartridge," writes Robert Cashner, author of The FN FAL Battle Rifle. "With millions of FALs manufactured and internationally distributed, the rifle played a large part in making the 7.62 x 51mm NATO the success that it was."
Vietnam is one often overlooked place where the FAL also proved a success. The weapon arrived there in the hands of Australian troops who fought as allies of the United States under the Southeast Asian Treaty Organization (SEATO).
More than 60,000 Aussies would serve in the Vietnam War from 1962 to 1972, including the 1st Battalion, Royal Australian Regiment. More commonly known as 1RAR, soldiers in the regiment fought in many significant battles during the war's escalation in the mid-1960s.
During those the engagements, they often faced well-equipped Viet Cong who carried new AK-47s supplied by the Communist Chinese and East Bloc nations.
Despite its weight and size (the FAL is one of the longest battle rifles of the 20th Century), 1RAR's troops considered their weapon suited for jungle warfare.
The powerful NATO round would punch through thick foliage, killing their concealed VC opponents. It was also a far more reliable weapon than the early version of the M-16 issued to U.S. forces – the FAL rarely jammed or misfired, two problems that plagued the M-16 for years.
