Players do not usually master all six skills, but rather focus on one or more of them in connection with the tactics employed by each team. The most common specialization comprises three positions: attacker/blocker (also differentiated in "outside" and "middle"), setter and liberos (defensive specialist).
Generally, taller players with the ability to jump high are utilized as attackers/blockers, where they attempt to block or spike opponents' initial hits and return the ball at high speed on steep trajectories so that the ball lands before the other team has time to react.
- Setters have the task for orchestrating the offense of the team. They aim for second touch and their main responsibility is to place the ball in the air where the attackers can place the ball into the opponents' court for a point. They have to be able to operate with the hitters, manage the tempo of their side of the court and choose the right attackers to set. Setters need to have swift and skillful appraisal and tactical accuracy, and must be quick at moving around the court.
- Liberos are defensive specialists, who are responsible for receiving the attack or serve (the dig ) and are usually the players on the court with the quickest reaction time and best passing skills. Librero means 'free' as they have the ability to substitute for any other player on the court during each play. They do not necessarily need to be tall, as they never play at the net, which allows shorter players with strong passing and defensive skills to excel in the position and play an important role in the team's success. A player designated as a libero for a match may not play other roles during that match. Liberos wear a different colour jersey than their teammates.
