Removing & adding player models in source sdk

[LordRevolution]

This is probably gonna sound stupid but im slowly learning the sdk and i would like to know how to
a. add some player models to the default list replacing the combine/rebel models
b. Change the default teams from rebels -> Humans, combine -> Aliens

**Edit i cant edit my post
Im making a mp mod and i honestly cant find where to add new pms in the code sorry if i sound noobish
Oh and i fixed the issue b so ignore that

**Edit
 Since 3D modelling is not my area of expertise i was simply wondering if somebody could put the human commando on human hl2dm animations

Make modelling "yours" by learning it. No-one would do things you want

Oh sorry
