Strategies:-
A Gear Doc's role is to act as the field mechanic. Blasting through the battlefield in its booster packs, the Gear Doc can quickly hover across to allies in need of repair or healing. Though weak and feeble, its ability to cloak when needed allows it to evade detection and possible destruction. The Gear Doc has slightly more armor, space and weight than that of the Medic thus allowing it to be able to reinforce its metal plating with armor.

Repair:-
Don't bring Gear Docs unless it is really needed. Gear Docs are easy to level and train as they do not require much battle participation points. Just repair or heal what is needed and stay at the battery pad (or methane springs). Do take caution that the enemy will be likely to attack your Gear Doc first as you can repair damaged or heal injured units. Be on the look out for Oizys and Boreas scouring the area for your Gear Doc. As soon as a group of Oizys or Boreas are sighted, call on the help of your fellow allies to use their AA to destroy the Oizys and Boreas.
