US Army history from the year you were born
US Army history from the year you were born
Much has changed since the 1920 amendment to the National Defense Act reorganized the United States Army. The U.S. Cavalry that fought in the Indian Wars has faded into history, those who protested for promised pay in post-World War I have died out, and the soldiers of the Greatest Generation who landed at Normandy Beach are almost gone.
To explore the fascinating history of the U.S. Army, Stacker scoured resources from newspaper articles and primary documents to studies and various governmental websites. Army strength numbers for each year are sourced from the Defense Manpower Data Center (DMDC).
Over the course of the last century, Army history has changed demographically, physically, and ideologically. Countries have fallen and risen, women are now permitted on the front lines of open combat, and training facilities have begun to employ video games to prepare recruits for 21st-century warfare. Women are also training in co-ed facilities, something unheard of 100 years ago when the world was still reeling from a war that had rocked the globe with its modern tactics and immense scope.
But the history of the Army isn’t only about warfare: During the Great Depression, it operated Civilian Conservation Corps (CCC) camps out of which previously unemployed, unmarried men worked on infrastructure programs designed to help stabilize a failing economy and provide jobs to those unable to find work.
The 1940s saw another war that affected the entire world. The U.S. was reluctant to get involved until the Pearl Harbor attack, which changed the national consensus and led the country to massively mobilize into stopping the Nazi regime and its allies. The 1950s was a decade that included the Korean War, nuclear testing, and Sen. Joseph McCarthy attacking the Army for being too easy on communists.
The 1960s brought another set of challenges. The Cold War began that decade, and Cuba became the face of America’s closest communist threat. Vietnam, a war that many protested, began with troops arriving in the country as early as 1965. From the 1970s to the 1980s, the U.S. struggled with recruitment and painting a new face on the Army. The 1990s and 2000s began a tech revolution, as well as fighting in the Middle East—which continues to this day. The U.S. Army has changed, but it endures and is still the main infantry force defending America.

1920: Amended National Defense Act is passed
- Army strength: 204,292 people (0.19% of U.S. population)
The National Defense Act of 1920 provided updates to the 1916 National Defense Act, including the reorganization of the U.S. Army as a three-part organization composed of the standing Regular Army, the National Guard, and the Organized Reserve. The act strengthened the National Guard and Organized Reserve in particular, stipulating that the Militia Bureau's chief be a National Guard officer and allowing National Guard officers to perform as Army general staff. Also in 1920, there was a big push for universal weight standards to ensure those who enlisted could meet the responsibilities of war.
1921: The Army intervenes at the Battle of Blair Mountain
- Army strength: 230,725 people (0.21% of U.S. population)
Four labor uprisings between 1919 and 1921 required Army intervention, but the largest of these—and the largest in U.S. history—took place over five days in late August and early September of 1921 as part of the Coal Mine Wars, multiple labor disputes throughout Appalachia.
Around 10,000 fully armed coal miners who sought to unionize marched to Logan County in West Virginia to confront 3,000 “Logan Defenders” (strike bearers backed by coal operators) and law-enforcement officers, and force the coal mines into a contract. Roughly 1 million rounds were fired, up to a 100 people killed (though this report varies), and many more arrested. The Army was deployed by a presidential order to stop the fighting and famously managed to send thousands of miners home without firing a single shot.

1924: Philippines scouts rebel
- Army strength: 142,673 people (0.13% of U.S. population)
Philippine scouts trained by members of the U.S. Army mutinied because they were not given the same pay and treatment as their stateside counterparts.

The U.S. Army ignored their requests for equal pay and changed nothing about recruitment methods or leadership.

The dog was an honorary member of the American Red Cross, YMCA, and American Legion. He sniffed out poison gas and tracked down wounded and dead soldiers, and survived shrapnel wounds and a gas attack over the course of 17 battles. He was the most highly decorated dog of World War I and so beloved that when he died, his body was preserved. He still wears his blanket decorated with his medals and can be seen at the Smithsonian Institution in Washington D.C.
1927: Joint Army and Navy Basic War Plan Red
- Army strength: 134,829 people (0.11% of U.S. population)
Surrounding the Geneva Naval Conference in 1927, the U.S. Army developed a series of color-coded war plans for hypothetical conflict scenarios with Japan, Germany, Mexico, and England. War Plan Red outlined a hypothetical plan for defending and invading British-held Canada. The plan described first sending the Joint Army in to capture Halifax in order to cut off Canadians from British allies before overtaking power plants around Niagara falls, causing Canadians to freeze. Mounting attacks—from marches into Montreal and Quebec to seizing nickel mines in Ontario—were intended to gain complete control.
War Plan Red was approved in 1930 by Secretary of War Patrick J. Hurley and Secretary of the Navy Charles Francis Adams III. Updates came to the war plan in 1934 and 1935, but it was never presented to Congress for an actual war declaration.
