When you prestige in cod4 do you unlock more classes?

Yes, when you prestige in Call of Duty 4: Modern Warfare, you do unlock additional class slots. After reaching the maximum level of 55 and choosing to prestige, you gain access to a new slot for creating custom classes, which allows for greater flexibility in loadout options. This process continues with each prestige, allowing for a total of up to 10 class slots once you've prestiged multiple times.
