NPCs as Allies

Source Interstellar Species pg. 151
You can also use NPCs in combat on the PCs’ side. Note that NPC statistics are best balanced to serve as adversaries against player characters, not against other NPCs. Also keep in mind the PCs should be the stars of most encounters—on top of which, it can also be wearisome for everyone at the table (including the GM) when a prolonged exchange takes place between two or more characters controlled by the same person.
However, having an NPC ally to provide covering fire, a temporary alternative target for a formidable foe, or a minor (or sometimes major) tactical advantage via a special ability at just the right moment can provide for some great storytelling moments and make the world of your adventures feel that much more authentic.
