As late as 1917, the United States maintained only a small army, one which was in fact smaller than those of thirteen of the states already active in the war. After the passage of the
Selective Service Act in 1917, it drafted 4 million men into military service. The
Commission on Training Camp Activities sought to improve the morals and morale of the troops. By the summer of 1918, about 2 million U.S. soldiers had arrived in France, about half of whom eventually saw front-line service; by the Armistice of November 11 approximately 10,000 U.S. soldiers were arriving in France daily. In 1917, Congress gave U.S. citizenship to
Puerto Ricans when they were drafted to participate in World War I, as part of the
Jones Act. The German Empire miscalculated the United States' influence on the outcome of the conflict, believing it would be many more months before U.S. troops would arrive and overestimating the effectiveness of U-boats in slowing the American buildup. Beginning with the
Battle of Saint-Mihiel, the first major battle involving the
American Expeditionary Forces, the leaders of the United States war efforts were General of the Armies
John J. Pershing,
Navy Admiral William Sims, and
Chief of Air Service Mason Patrick. hurling hand grenades into the Austrian trenches The
United States Navy sent a

Scapa Flow to join with the British

submarines to help guard convoys. Several regiments of
Marines were also dispatched to France. The British and French wanted U.S. units to be used to reinforce their troops already on the battle lines and not to waste scarce shipping on bringing over supplies. The U.S. rejected the first proposition and accepted the second. General John J. Pershing,
American Expeditionary Forces (AEF) commander, refused to break up U.S. units to serve as mere reinforcements for
British Empire and French units. As an exception, he did allow the African-American combat regiments that made up the 93rd Combat Division to fight in French divisions. This allowed him to fulfill his pledge to provide the French military with troops while appeasing the black combat regiments, indignant at the fact that they couldn't fight on the front lines.
African Americans in the military , April 1918. Around 400,000 black men were enlisted in the military from 1917 to 1918 with half of these men being sent to Europe. However, with the exception of the 42,000 men in the 92nd and 93rd Combat Divisions, the majority of African Americans weren't permitted to serve in active combat roles as white officers believed that black men lacked the 'mental stamina and moral sturdiness' that a front line soldier required. Those enlisted in the army and sent to Europe most commonly served in
labour battalions under the banner of
Services of Supply (SOS). The African Americans placed in these units often spent their days doing tough labour like unloading supplies from ships or transporting goods from ports to warehouses near the front lines. These battalions were also tasked with building warehouses, roads, railroads and other vital infrastructure near major ports like
Brest,
Bordeaux,
Marseilles, and
St. Nazaire. The men who served in these units were faced with some of the worst living conditions of all US soldiers due to
racial segregation enforced by white officers. In the first couple of months after their arrival to Europe, many black soldiers reported that they had to sleep in tents on the dirt floors of
barracks, eat outside, rather than in canteens, use makeshift outhouses, and wash themselves in makeshift bathrooms. This was done because African Americans saw the war effort as an opportunity to prove their patriotism and loyalty to the United States. Many hoped that by involving themselves in the war they would win expanded rights on the home front. This did not end up entirely occur as the race riots that followed the armistice in the
Red Summer. An outcome of the service, sharpened the politics of African American soldiers. Many returned home referring to themselves as the
New Negro. These men experienced life without the restrictions of second-class citizenship, as French civilians treated them kindly when they went outside of the segregated military camps. Many returned home to America with a new fighting spirit, determined to earn expanded rights. During the course of the war, 21,498 U.S. Army nurses (American military nurses were all women then) served in military hospitals in the United States and overseas. Many of these women were positioned near to battlefields, and they tended to over a million soldiers who had been wounded or were unwell. 272 U.S. Army nurses died of disease (mainly tuberculosis, influenza, and pneumonia). Eighteen African-American Army nurses, including
Aileen Cole Stewart, served stateside caring for German prisoners of war (
POWs) and African-American soldiers. They were assigned to
Camp Grant, IL, and
Camp Sherman, OH, and lived in segregated quarters. receive decorations
Hello Girls was the colloquial name for American female
switchboard operators in World War I, formally known as the Signal Corps Female Telephone Operators Unit. During World War I, these switchboard operators were sworn into the
Army Signal Corps. This corps was formed in 1917 from a call by General
John J. Pershing to improve the worsening state of communications on the Western front. Applicants for the Signal Corps Female Telephone Operators Unit had to be bilingual in English and French to ensure that orders would be heard by anyone. Over 7,000 women applied, but only 450 women were accepted. Many of these women were former switchboard operators or employees at telecommunications companies. they were not given
honorable discharges but were considered "civilians" employed by the military, because Army Regulations specified the male gender. Not until 1978, the 60th anniversary of the end of World War I, did Congress approve veteran status and honorable discharges for the remaining women who had served in the Signal Corps Female Telephone Operators Unit. The first American women enlisted into the regular armed forces were 13,000 women admitted into active duty in the U.S. Navy during the war. They served stateside in jobs and received the same benefits and responsibilities as men, including identical pay (US$28.75 per month), and were treated as veterans after the war. The U.S. Marine Corps enlisted 305 female Marine Reservists (F) to "free men to fight" by filling positions such as clerks and telephone operators on the home front. During World War I,
Myrtle Hazard enlisted in the Coast Guard, served as a telegraph operator, and was discharged as an Electrician 1st Class. She was the only woman to serve in the Coast Guard during the war and she is the namesake of
USCGC Myrtle Hazard. Wartime newspapers erroneously reported that twin sisters Genevieve and Lucille Baker were the first women to serve in the Coast Guard. While they tried to enlist, they were not accepted. These women were demobilized when hostilities ceased, and aside from the Nurse Corps the uniformed military became once again exclusively male. In 1942, women were brought into the military again, largely following the British model.

Motor vehicles 'Model B', 3-ton, 4x4 truck Before the American entry into the war, many American-made heavy
four-wheel drive trucks, notably made by
Four Wheel Drive (FWD) Auto Company, and
Jeffery / Nash Quads, were already serving in foreign militaries, bought by Great Britain, France and Russia. When the war started, motor vehicles had begun to replace horses and
pulled wagons, but on the European muddy roads and battlefields, two-wheel drive trucks got stuck all the time, and the leading allied countries could not produce 4WD trucks in the numbers they needed. The
U.S. Army wanted to replace four-
mule teams used for hauling standard 1
U.S. ton (3000 lb / 1.36
metric ton) loads with trucks, and
requested proposals from companies in late 1912. This led the
Thomas B. Jeffery Company to develop a competent four-wheel drive, 1 short ton capacity truck by July 1913: the "Quad". , c. 1916 The Jeffery Quad truck, and from the company's take-over by
Nash Motors after 1916, the
Nash Quad, greatly assisted the World War I efforts of several Allied nations, particularly the French. The U.S. first adopted Quads in the
USMC's occupations of Haiti, and
the Dominican Republic, from 1915 through 1917, as well as in the 1916
Pancho Villa Expedition against Mexico. Once the U.S. entered World War I, general John Pershing used Nash Quads heavily in the European campaigns. They became the workhorse of the Allied Expeditionary Force there — both as regular transport trucks, and in the form of the
Jeffery armored car. Some 11,500 Jeffery / Nash Quads were built between 1913 and 1919. driving a Model B, FWD truck – promotional photo. The success of the
Four Wheel Drive cars in early military tests had prompted the U.S. company to switch from cars to truck manufacturing. For World War I, the U.S. Army ordered an amount of 15,000
FWD Model B, three-ton (6000 lb / 2700 kg) capacity trucks, as the "Truck, 3 ton, Model 1917", with over 14,000 actually delivered. The British Army purchased 2929 trucks, with 1599 of them used on the Western Front. Once the FWD and Jeffery / Nash four-wheel drive trucks were required in large numbers in World War I, both models were built under license by several additional companies to meet demand. The FWD Model B was produced under license by four additional manufacturers. The Quad and the FWD trucks were the world's first four-wheel drive vehicles to be made in five-figure numbers, and they incorporated many hallmark technological innovations, that also enabled the decisive U.S. and Allied usage of 4x4 and 6x6 trucks subsequently in World War II. The Quad's production continued for 15 years with a total of 41,674 units made. Socially, it was the FWD company that employed
Luella Bates, believed to be the
first female truck driver, chosen to work as test and demonstration driver for FWD, from 1918 to 1922. During World War I, she was a test driver traveling throughout the state of Wisconsin in an FWD Model B truck. After the war, when the majority of the women working at Four Wheel Drive were let go, she remained as a demonstrator and driver. ==Postwar and occupation==
