Input: Question: How long did the operation last in which Post was stationed at an air base in Qatar? Passage 1:Since the 1990s, United States college soccer has played a significant role in the development of New Zealand players. This influence began when former Scotland international Bobby Clark returned to the U.S. after his 199496 stint as New Zealand head coach to take the head coaching job at Stanford University (he now holds the same position at Notre Dame). Clark began recruiting in New Zealand, and former New Zealand national players Ryan Nelsen and Simon Elliott played for him at Stanford. The trend that Clark started has continued to the present; more than two dozen New Zealanders are now playing for NCAA Division I men's programs in the U.S. A common next step in these players' career paths is a stint in Major League Soccer; ESPN soccernet journalist Brent Latham speculated in a March 2010 story that New Zealand's 2010 FIFA World Cup squad could have more MLS players than the U.S. squad. However, Latham's speculation did not prove true, as only one MLS player made the New Zealand squad for the World Cup. New Zealand formerly competed against Australia for top honours in the OFC. However, after Australia left to join the AFC in 2006, New Zealand were left as the only seeded team in the OFC. New Zealand qualified for the 2010 FIFA World Cup though exited the competition after the first round despite being the only team not to lose a game during the tournament. The tournament also featured one of New Zealand's most notable results, a 11 draw with the then world champions Italy. New Zealand drew their other two pool games with Slovakia and Paraguay and ultimately finished above Italy, who placed last, in the group. New Zealand drew all three games and finished third in their group. New Zealand were also the only undefeated team in the entire tournament thanks to Spain's defeat to Switzerland.
Passage 2:From July 1996 to May 1997, Post was a student at the Army Command and General Staff College at Fort Leavenworth, Kansas.

He was an F-16 Evaluation Pilot with the 77th Fighter Squadron, Operations Officer with the 79th Fighter Squadron, and then commander of the 55th Fighter Squadron, all at Shaw Air Force Base in South Carolina. From July 2002 to June 2003, he was a student at the Air War College at Maxwell Air Force Base, earning a Master of Strategic Studies degree. He was Senior Deputy Commander of the 56th Operations Group at Luke Air Force Base from July 2003 to March 2004, and Vice Commander of the 388th Fighter Wing at Hill Air Force Base in Utah from April 2004 to July 2006. He was in charge of Standardization and Evaluation with the Twelfth Air Force at Davis-Monthan Air Force Base in Arizona from August 2006 to January 2007. He commanded the 20th Fighter Wing at Shaw Air Force Base from February 2007 to October 2008, and then the 609th Air and Space Operations Center at Al Udeid Air Base in Qatar in support of Operation Iraqi Freedom. He flew 280 combat sorties. From August 2009 until January 2010, he was Director of Plans and Requirements at Headquarters, Twelfth Air Force.
