Jeff Monken, who was 38-16 at Georgia Southern, was hired as head coach at Army.
Monken will be formally introduced at a press conference at West Point on Monday.
Monken is an offensive-minded coach who runs the triple-option system familiar to the program. Georgia Southern reached the FCS semifinals three times in Monken's four seasons in Statesboro and knocked off Florida, 26-20, in 2013.
I am thrilled to accept the head coaching position at West Point," Monken said in a statement released by the school. "Not only is the United States Military Academy one of the most prestigious academic institutions in the world, it boasts one of the nation's richest, most historic traditions in all of college football. I am anxious to get started."
Monken worked under Paul Johnson as an assistant at Navy and Georgia Tech. Johnson previously worked at Georgia Southern before leaving for the Navy job.
"We want a successful head coach who understands the challenges of working at a service academy, one who could help us win immediately and one who understands the importance of West Point's mission. We found that in Jeff," Army athletic director Boo Corrigan said. "Jeff has been highly successful at every stop he has made both on the field and off. We expect him to experience that same level of success at West Point. We could not be more excited to have Jeff, his wife Beth, and their three daughters join the West Point family and lead our football program."
