The defense is made up of three defenders. At the youth level, defenders use short sticks (30" shafts), from middle school and up, defenders play with long sticks (60" shafts). The defense can only play in the defensive half of the field. Typical defenseman are tall and strong, which helps to keep attackmen from scoring goals. Since defenders do not take very many checks, most use very short arm pads. A defender's job is to not let offensive players score a goal. A defender does this by checking an offensive player's stick to try to dislodge the ball and also use his body to check a player.
