No... When he says hoo ha, it is actually spelled (to a certain degree) hooah! It's an army term pretty much meaning affirm. For example.. if a drill instructor tells you that he wants you to take that hill, you say Hooah! and then you go run and take that hill. It also mean you heard what he said... "Tomorrow at 0800 we are going to have a locker box inspection" Then everyone says "Hooah!"
"Hooah" can be found in the scripts of several military-related movies. One well-known example is Al Pacino's character, a former U.S. Army officer, in the movie Scent of a Woman (which may have popularized the longer "Hoo-Ah" version). "Hooah" also features prominently in Black Hawk Down, which depicts United States Army Rangers at the 1993 Battle of Mogadishu, Somalia and Lions for Lambs a film about the war in Afghanistan. In Basic, Samuel L. Jackson's character finishes each line of his training briefings with "Give me a 'Hooah', Sergeant!". In the 2004 American film The Manchurian Candidate, Denzel Washington's character responds an order with it during the brainwashing procedure. It is also extensively used by Matt Damon's character in the 2010 movie Green Zone.
