Freelancers are mercenaries that are not a part of any band or group. They opearate on their own and will work for anyone who is offering credits. They

make a short appearance in the mission Dossier: Archangel in Mass Effect 2.

Freelancers have no shields or armor and generally wield assault rifles. They are very easy to take out. Take cover and fire a couple of controlled bursts and the freelancers will fall in no time.
