"This field medic learns more about biology and Logos combinations. Squads looking to maximize their staying power while limiting that of their enemies should look to add a Biotechnician to their group.
Biotechnicians stem from the Specialist line. These troops push survivability to even greater heights; they can restore health to entire groups, improve group healing rates, and are generally significant assets to large squads. Tier-four training leads Biotechnicians into an ultimate squad-support role for Medics. Alternatively, the Exobiologist path offers heavy support abilities and a few additional attack options."
