Question: How long did William D. Swenson serve in the army? Passage 1:Huitema made her first junior appearance for Canada with the national under-15 team on August 7, 2014 against Puerto Rico in a 5–0 victory at the CONCACAF Girls Under-15 Championship. The Canadians would go on to win the inaugural edition of the tournament in a penalty shoot-out, with Huitema scoring the winning shoot-out goal. She would go on to make 10 more appearances for the under-15 squad. Huitema's debut for the under-17 team came on March 3, 2016 at the CONCACAF Women's Under-17 Championship in a 3–0 win against Guatemala. Huitema played in the 2016 FIFA U-17 Women's World Cup. There, she scored her first goal in FIFA competition in a 3–2 win over Cameroon. She made 7 more appearances for the under-17 team. On July 6, 2017, Huitema made her first appearance for the under-20 team, scoring a goal in a 4–1 win over the United States. After scoring in a 3–1 loss to China in an under 17 match on July 12, 2017, Huitema became the first Canadian to score for the under 17, under 20 and senior national team in the same calendar year. In 2017, she was named the Canada U17 Female Player of the Year for her performances with the U-17, U-20 and senior teams throughout the year. On January 12, 2018, Huitema was named to Canada's squad for the 2018 CONCACAF Women's U-20 Championship in Trinidad & Tobago. In the first game of the tournament, Huitema scored twice in a 3–1 win over Costa Rica. In the second game, Huitema scored a hat-trick in a 4–1 win over hosts Trinidad & Tobago, which clinched Canada's progress into the semi-finals. She would play 66 minutes in a 4–0 victory over Haiti which resulted in Canada winning their group. In the semi-finals against Mexico, Huitema played the full game in a 1–1 draw. Canada would lose the match 4–3 on penalty kicks in which Huitema saw her attempt saved. Canada would require a win over Haiti in the third place match to qualify for the FIFA U-20 Women's World Cup in France later in the year. Canada would lose the match by a score of 1–0 and fail to qualify for the U-20 World Cup. Huitema was the tournament's top scorer with five goals and was named to the Best XI of the championship.
 Passage 2:Due to his actions during the battle, former Army Captain William D. Swenson was recommended to receive the Medal of Honor by Marine General John R. Allen. Having been critical of the officers superior to him during the battle, he left the Army in February 2011. A 2012 investigation by McClatchy News Service concluded that the justification for Meyer's decoration may have been inflated and that the nomination for Swenson's Medal of Honor may have been intentionally lost. Meyer disputes McClatchy's allegations in his book, Into the Fire: A Firsthand Account of the Most Extraordinary Battle in the Afghan War. In August 2012, California Representative Duncan D. Hunter wrote to Secretary of Defense Leon Panetta regarding the Medal of Honor nomination of Swenson, comparing his case to that of Sgt. Rafael Peralta. In January 2013, Representative Hunter said Swenson's nomination had been awaiting President Barack Obama's approval at the White House since at least July 2012. Representative Hunter stated he was considering seeking an inspector general inquiry due to the delay. Swenson was awarded the Medal of Honor on October 15, 2013.
 Passage 3:During World War I (1914–18) an expanded Force Publique served against German colonial forces in the Camerouns and German East Africa (Tanzania, Rwanda, Burundi), as part of the East African Campaign. The Force Publique performed well on the battlefield, winning the respect of their British and Portuguese allies, as well as that of their German opponents. 1916 onwards, the Force Publique grew to reach a strength of three mobile Groupes (brigades), Kivu, Ruzizi, and Tanganyika, comprising a total of 15 battalions, from the static garrison and police force of 1914. However, it did take until late 1915 for the Force Publique to finish preparations for a large scale offensive on the German colony of German East Africa. The allied powers, the British Empire and Belgium launched a coordinated attack on the German colony, by 1916 the Belgian commander of the Force Publique, Lieutenant-General Charles Tombeur, had assembled an army of 15,000 men supported by local bearers and advanced to Kigali. Kigali was taken by 6 May 1916. The German army stationed in Burundi was forced to retreat by the numerical superiority of the Belgian army and by 17 June 1916, Burundi and Rwanda were occupied. The Force Publique and the British Lake Force then started a thrust to capture Tabora, an administrative centre of central German East Africa. The army went on to take Tabora on 19 September after heavy fighting. At the time of the Battle of Tabora in September 1916 about 25,000 men were under arms, during the war their actions were supported by more than 260,000 local bearers. In 1916 Charles Tombeur was made Military Governor of the Belgian Occupied East African Territories. After the Mahenge Offensive and the capture of Mahenge in 1917, the Belgian Congolese army controlled roughly one-third of German East Africa. After the war, as outlined in the Treaty of Versailles, Germany was forced to cede "control" of the Western section of the former German East Africa to Belgium. On 20 October 1924, Ruanda-Urundi (1924–1945), which consisted of modern-day Rwanda and Burundi, became a Belgian League of Nations mandate territory, with Usumbura as its capital.
