Where are the meshes, Aliens, Humans weapons, etc?

For my own curiosity I'd like to see the meshes that tremulous uses,
weapons, characters etc.
I'm not sure where they are stored, is it a PK3 in the folder "Base"?

This should go in the models section maybe....

Also, here is a post from a thread in the models section.
