many vehicles, fighting alone can only lead to a melee

Since Battlefield 2 the game has introduced a squad system. Squad leaders can give orders to their team members, while squads can respawn around the squad leader. In addition, squads can talk to each other internally by voice, so squads can form a flexible, powerful combat unit for missions. Players can also choose not to join any squads and fight "lone wolf", but this is generally less efficient.
