The quarterback, colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive platoon and mostly line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack.
A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover receivers most of the time, but also blitz and defend against such offensive running plays as sweeps and reverses. They create turnovers through hard tackles, interceptions, and deflecting forward passes.
Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and line up three to five yards behind the line of scrimmage and the defensive linemen. They are the "middle ground" of defenders, playing closer to the line of scrimmage than the defensive backs (secondary), but farther back than the defensive linemen.
In gridiron football, a sack occurs when the quarterback is tackled behind the line of scrimmage before throwing a forward pass, when the quarterback is tackled behind the line of scrimmage in the "pocket" and without clear intent, or when a passer runs out of bounds behind the line of scrimmage due to defensive pressure. This often occurs if the opposing team's defensive line, linebackers or defensive backs are able to apply pass pressure to quickly get past blocking players of the offensive team, or if the quarterback is unable to find a back to hand the ball off to or an available eligible receiver to catch the ball, allowing the defense a longer opportunity to tackle the quarterback.

Nine-man football is a type of American football played by high schools that are too small to field teams for the usual 11-man game. In the United States, the Minnesota State High School League, North Dakota High School Activities Association, South Dakota High School Activities Association, and Wyoming High School Activities Association hold high-school state tournaments in nine-man football. It is the earliest attested reduced-man variant of football, being attested as early as 1889 in an Amateur Athletic Union-sanctioned college football game at the original outdoor Madison Square Garden.

A halfback (HB) is an offensive position in American football, whose duties involve lining up in the offensive backfield and carrying the ball on most rushing plays, i.e. a running back. When the principal ball carrier lines up deep in the backfield, and especially when that player is placed behind another player (usually a blocking back), as in the I formation, that player is instead referred to as a tailback (TB).
Safety is a position in gridiron football on the defense. The safeties are defensive backs who line up ten to fifteen yards from the line of scrimmage. There are two variations of the position: the free safety and the strong safety. Their duties depend on the defensive scheme. The defensive responsibilities of the safety and cornerback usually involve pass coverage towards the middle and sidelines of the field. While American (11-player) formations generally use two safeties, Canadian (12-player) formations generally have one safety and two defensive halfbacks, a position not used in the American game.
In American football, the 3–4 defense is a common defensive alignment consisting of three down linemen and four linebackers.

Alternatively, some defenses use a 4–3 defense: four down linemen and three linebackers.
