Call of Duty 3/Classes

Moving away from the game-play style of previous Call of Duty games, where players would simply select a team and weapon, Call of Duty 3 multiplayer bears closer similarity to that of Battlefield 1942, in that players select a class of soldier and a team, the chosen class defining both the player's weaponry and the unique abilities that he or she will hold over the other classes. There are seven classes of soldier to choose from, with different weapons (although of similar specifications) depending on which side the player fights. Every class has a sprinting action used instead of the normal binoculars used when the usual binocular button (during single player mode) is pressed.

Classes include riflemen, light and heavy assault, medic, scout, support and anti-armor. Players select a class when entering a match, but can change classes after they have been killed. Each class has a primary weapon, a pistol, and a unique ability, such as reviving team mates as a medic, calling in artillery as a scout, laying mines as light or heavy assault, giving ammunition as anti-armor or support, or firing rifle grenades as a rifleman. Players cannot change classes until they have died, but they can pick up dropped weapons to replace their starting pistol.
