In football, an Aggie refers to a player or fan of the Texas A&M Aggies football team. The Texas A&M Aggies football program represents Texas A&M University in the sport of American football and competes in the Football Bowl Subdivision (FBS) of the National Collegiate Athletic Association (NCAA) and the Western Division of the Southeastern Conference (SEC). Aggie football fans call themselves the 12th Man, meaning they are there to support the 11 players on the field. To further symbolize their "readiness, desire, and enthusiasm," the entire student body stands throughout the game. In a further show of respect, the students step "off the wood" (step off the bleachers onto the concrete) whenever a player is injured or when the band plays the Aggie War Hymn or The Spirit of Aggieland. The Fightin Texas Aggie Band, the largest military-style marching band in the United States, performs at halftime during the football games. The term Wrecking Crew is a name given to defenses of the football team.
