Army has hired Jeff Monken as its football coach.
Monken spent the last four seasons at Georgia Southern after learning the triple-option offense under Paul Johnson during stints as an assistant at Navy and Georgia Tech.
Monken posted a 38-16 record at Georgia Southern and helped guide the program's transition to the Football Bowl Subdivision from the Football Championship Subdivision ranks.
Georgia Southern, which will join the Sun Belt Conference next year, qualified for the NCAA playoffs in all three eligible seasons under Monken, advancing to the national semifinals each year while posting double-digit victory totals.
Monken will be officially introduced during a news conference Monday. He replaces Rich Ellerson, who was fired last week after his fifth straight loss to Navy.
