Slogans of the United States Army
“Army of One” was a relatively short-lived recruiting slogan. It replaced the popular “Be All You Can Be” and was replaced in 2006 by the new slogan “Army Strong”. The reason for the replacement is believed to be[by whom?] that the slogan “Army of One” is contrary to the idea of teamwork.It is unknown whether this slogan was taken directly from the poster for the 1976 Clint Eastwood film “The Outlaw Josey Wales,” which had “An Army of One” under a drawing of the Josey Wales character.
