Question: How many people died in the same combat that killed Colleen's uncle? Passage 1:The United States Navy dog handler hazing scandal was a pattern of misconduct engaged in by members of the United States Navy at Naval Support Activity Bahrain between 2004 and 2006. Naval investigators documented nearly 100 incidents of abuse committed against several members of a Military Working Dog (MWD) unit stationed at the United States military base at Juffair. Documented incidents of abuse include racial intimidation, sexual harassment, physical abuse and anti-gay harassment. One sailor, Master-At-Arms 3rd Class Joseph Rocha, suffered post-traumatic stress disorder because of his abuse at the hands of fellow sailors, and he alleges that another sailor committed suicide because of her treatment. The Navy investigated the allegations in 2007 and documented the abuse, but took little substantive action. However, Pennsylvania Congressman Joe Sestak, a former Vice Admiral, demanded a new examination of the report's findings which led to the disciplining of Rocha's former superior, Chief Petty Officer Michael Toussaint (later Senior Chief Petty Officer). The scandal came to widespread public attention as United States President Barack Obama faced increased pressure to repeal the military's gay-exclusionary policy known as "don't ask, don't tell" (DADT).
 Passage 2:Before 1953, Walt Disney's productions were distributed by Winkler Pictures, Powers Pictures, Universal Pictures (Oswald the Lucky Rabbit shorts), Columbia Pictures (1930–1932), United Artists (1932–1937) and RKO Radio Pictures (1937–1953). However, a dispute over the distribution of Disney's first full-length movie, The Living Desert, in the True-Life Adventures series of live-action documentary featurettes in 1953 led to Walt and his older brother Roy O. Disney to form its wholly owned subsidiary, the Buena Vista Film Distribution Company, Inc. (BVDC), to handle North American distribution of their own products. RKO refused to distribute the film. The name "Buena Vista" came from the street in Burbank, California, where the Disney Studios was located (and remains to this day). Buena Vista's first release was the Academy Award–winning live-action feature The Living Desert on November 10, 1953, along with Toot, Whistle, Plunk and Boom, Buena Vista's first animated release. Notable subsequent releases include the foreign film, Princess Yang Kwei-Fei (Most Noble Lady), released in US theaters in September 1956, The Missouri Traveler in March 1958, and The Big Fisherman in July 1959 (the first third-party production financed by Disney).
