and other achievements. In Battlefield 2, players are divided into two opposing teams (which factions they represent is dependent upon the map). The key objective in Battlefield 2 is to reduce the opposing teams tickets. Tickets represent an army's ability to reinforce their position on the battlefield; each team has only a limited supply of tickets, and each casualty on the battlefield reduces the number of available tickets. Control points represent key points on the map, and are represented by flags. Control points are Battlefield 2s spawn points, and one team possessing a significant majority of the control points causes the other teams tickets to gradually decrease, regardless of casualties. A round ends when one team's tickets gone, the round's timer ends, or if at any point a team holds no control points, and has no soldiers alive on the battlefield (meaning they are not present in any way on the battlefield). Battlefield 2s two game modes are Conquest and Cooperative. The only difference between the two modes is that Cooperative includes computer-controlled players, whilst Conquest allows only human players. Results from Cooperative mode do not count toward global player statistics. Infantry classes In Battlefield 2, as with previous Battlefield titles, players are able to select from a variety of infantry classes. Each class of soldier is equipped with different weaponry appropriate to their role in the battle. Assault soldiers, for example, are general-purpose infantry with grenade-launcher equipped assault-rifles and extra armor, Medics carry first-aid equipment such as a field defibrillator, and Anti-Tank troopers are equipped with missiles which are effective against heavy armor. Players are able to choose a class at the start of a match, or between dying and respawn. Players can also change their class by picking up a "kit" from the body of an incapacitated soldier, friendly or otherwise. Hence, an Assault soldier can become a Medic if they come across a fallen Medic. Player classes are divided in 'Heavy' (with reduced damage done to the torso, but lower stamina) and 'Light' (with standard multipliers, but higher stamina, thus able to sprint for a longer time). Within the infantry class, there are four support classes with special abilities. The Engineer can repair with his wrench, the Medic can revive with his defibrillator paddles and heal, the Support can resupply ammunition with his ammunition bags and the sniper can place claymores and engage long distance targets.
