Weapon selection screen in MP?

[Gadjuka]

Does anyone know how you in description.ext define which weapons/ammo the players should be able to choose from in MP?
OBS. I mean for the different sides: The west-players should not be able to select an AK-74, and a east-player shouldn't be able to choose an M60.

I would imagine the easier way would be to put in ammo crates where the units start the game.
