Mark Moyar, an associate professor at the U.S. Marine Corps University feels that Halberstam and Sheehan, along with other reporters, "horribly tarnished the reputations of some very fine Americans, including General Harkins". Moyar writes that others, such as John Mecklin (then on leave from "Time" as Public Affairs officer for the US embassy) observed Harkins living a "Spartan" life in Saigon and traveling "daily" by small plane around the country to gather and evaluate information from South Vietnamese and American troops. Moyar observes that, while Harkins was not a "creative or brilliant strategist", he was a "superb motivational and technical coach, which was what the situation most demanded".
