A libero is a defensive player that plays only in the back row. Liberos are not allowed to serve, according to the USA rules, but they are allowed to hit from the back row. When a libero goes into or comes out of the game, it is not counted as a substitution. Also, liberos do not have to go in and come out for the same person every time.

A Libero is a volleyball player specialized in defensive skills. The libero is allowed to "sub" in and out for a back-row player at any time without stopping the play. They are known for their defensive abilities. They are only allowed to forearm pass the ball when they are in front of the attack line. They are not allowed to play in the front row. Liberos are signified on the court by wearing jerseys that contrast to the colors of their teammates. Libero rules vary depending on the level of play. In the high school level of girl's volleyball, liberos can serve. In club however in juniors, liberos cannot serve. They may sub behind the ten foot line after the play has concluded without going to the substitution line. A libero cannot attack the ball or else it is considered a "back row attack". They may hit they ball but may not jump above the net. If they hand set the ball in front of the ten foot line the hitter may not jump above the net to attack the ball or else it is also considered a back row attack, which is illegal.

Yes, the libero can serve in volleyball. However, they can only serve for one position. Once the libero serves in a particular position in a game that is the only position where the libero is allowed to serve. However, the libero is not required to serve in that position for all subsequent rotations.
