Question: Which Major General served longer in the military, Wade Haislip or John Coulter? Passage 1:On 15 May 1942, five months after the United States entered World War II, the 85th Infantry Division was ordered into active military service at Camp Shelby, Mississippi, under the command of Major General Wade H. Haislip. Divisions in the U.S. Army at that time were "triangularized" with three combat regiments instead of the four regiment structure "square division" used during World War I. The 340th Infantry Regiment was redesignated as the 410th Quartermaster Battalion and left the division. Basic infantry training was begun in June 1942 at Camp Shelby, Mississippi. In April 1943, it participated in large-scale army training in the Louisiana Maneuvers near Leesville, Louisiana. In August, the division was moved to Camp Coxcomb, California for desert warfare training. In October, the division was transferred to Fort Dix, New Jersey, for final preparations before shipment overseas. Major General John B. Coulter was transferred as commander and retained this position throughout the war. The Assistant Division Commander (ADC) throughout the war was Brigadier General Lee S. Gerow.
 Passage 2:Though his parents were from Cortland, New York, Dio was born in Portsmouth, New Hampshire, where his family resided for his father's service in the U.S. Army during World War II; they soon returned to Cortland. Dio's music career began there in 1957 as part of the Vegas Kings (later Ronnie and the Rumblers). In 1967, he formed the rock band Elf, which became a regular opening act for Deep Purple. In 1975, Deep Purple guitarist Ritchie Blackmore founded the band Rainbow and hired Dio to be his lead singer where the band released three studio albums. Dio quickly emerged as one of heavy rock's pre-eminent vocalists. In 1979, Dio joined Black Sabbath as lead singer. He appeared on three studio albums with the band which met with success: Heaven & Hell (1980) and Mob Rules (1981) and Dehumanizer (1992). In 1982, he left the band to pursue a solo career with two albums certified platinum by RIAA. In 2006, he founded the band Heaven & Hell with ex-bandmate Tony Iommi. Dio was diagnosed with stomach cancer in 2009, from which he died the following year.
 Passage 3:Vance Astro first appeared as a founding member of the Guardians of the Galaxy. According to Roy Thomas, all of the Guardians of the Galaxy were created in a conference between Arnold Drake and Stan Lee, but it remains uncertain whether each individual character was created by Drake, Lee, or both. The Guardians of the Galaxy debuted in the partial reprint title Marvel Super-Heroes with issue #18 (Jan. 1969), written by Drake and penciled by Gene Colan. After five years' absence, he was revived in several Marvel titles: Marvel Two-In-One #4-5 (July-Sept. 1974), Giant Size Defenders #5, and Defenders #26-29 (July-Nov. 1975). In each case, other heroes such as Captain America, the Thing, and the Defenders aid Astro and the Guardians against the alien Badoon. The first story established that if Vance Astro's containment suit were breached, he would age 1,000 years in a second. This drew numerous queries from readers, and the letters page in Marvel Two-in-One #7 responded by stating that Vance feeds and defecates intravenously. The Guardians were also featured in Marvel Presents #3-12 (Feb. 1976 - Aug. 1977).
