Support Class players can quickly span the map with their forces to help their allies through speedy aircraft, support powers, and destructive strikes. While the Support Class is very quick, many of their units are not armored enough to take on enemy forces head to head as easily as the Offense Class. However, teching up to tier 3 will give you access to the mighty GDI Kodiak or Nod Leviathan, the slow moving nightmares of the skies. Support Powers consume Support Points that charge up throughout the match in three different ways – naturally over time, buffing allies or debuffing enemies, and dealing damage. The Support Class has the most tricks up their sleeves, offering countless strategies to anyone who can master their massive toolset. Play as a medic and heal your teammates or build Firehawks to bomb your enemies into oblivion – the possibilities are endless.
