Specific NPCs friendly to specific playermodel

I don’t know how to edit the code for this, but what I want is the Warhammer 40k marines from Dan’s Mega NPC Pack (http://www.garrysmod.org/downloads/?a=view&id=57642) to be friendly towards the Space Marine Playermodel (http://www.garrysmod.org/downloads/?a=view&id=67975).

And I don’t know, maybe someone could even make an RP with this.

I’m pretty sure it would be easier to make the npc’s to be friendly towards a team and set the playermodel for that team to a specific one.

Okay, how do I do that?
