In American football the air raid offense refers to an offensive scheme popularized by such coaches as Hal Mumme, Mike Leach, Sonny Dykes, and Tony Franklin during their respective tenures at Iowa Wesleyan University, Valdosta State, Kentucky, Oklahoma, Texas Tech, Louisiana Tech, and Washington State.
The system is designed out of a shotgun formation with four wide receivers and one running back. The formations often feature two outside receivers and two inside slot receivers. The offense also uses trips formations featuring three wide receivers on one side of the field and a single receiver on the other side.
