These soldiers are the go-anywhere, fight-anything special forces of the Alliance that were trained at the Interplanetary Combatives Academy in Rio de Janeiro, Brazil. They had to survive combat situations "in an admirable and effective fashion" to receive the N7 rank. Many N7s now train other species in anti-Reaper asymmetric warfare. The Demolisher uses grenades to attack at range and to terrorize the battlefield. Demolishers can also create a supply pylon that stocks allies with an unending reserve of grenades and thermal reloads.
