You Talkin’ to Me, Sarge?

According to Neil Howe, a historian widely credited with inventing the term "millennial generation," military recruitment ads illustrate the differences between Generation Xers and millennials. Whereas Gen X recruitment focused on personal challenge and conquest, the message for millennials is "why we're fighting in the first place."

Howe, the author of "Millennials in the Workplace" and a blogger for The Huffington Post, said that this generation wants to be on a team that is more than the sum of its parts. "The drill sergeant won't yell at millennials when they get off the bus for basic training," he said. "They will thank them for their service in a time of war."
