Fastest way to gain xp COD4

Wichmode in Cod4 MPdo you think is the fastest one to gain xp. Thx for answering ?

I just play TD.

Just keep playing. You only gain XP, you cant loose it so there's no sense in really asking what is the better way.

Im partial to sitting back in a bush with my lovely Dragonov :)

I've sprayed so many people like you in the face with my MiniUzi!

fastest i think is S&D and headquarters.
