In order to prolong the survival of their armored divisions as well as sustain the momentum of the attack, the Allied Forces during Second World War created the field mechanic corps, whose sole duty was to maintain Allied vehicles literally in the field of battle. These mechanics performed with distinction at their job and managed to save countless tanks and crews on the battlefield.
However, due to the nature of their equipment and training, field mechanics carried absolutely no weapons and were defenseless against enemy fire and had to be protected by infantry or combat vehicles at all times.
The Mechanic functions like a Medic, but it works on vehicles and not on infantry. If a mechanic was to enter a transport such as an APC, he had to repair it before entering, probably due to engine limitations.
Though expensive, mechanics repair vehicles much faster than the Service Depot and will do so for free. Having a few mechanics in tow with armored forces is often vital for a moving force and are the answer to quickly restore them from the occasional shockwaves of MAD tanks. However, as with the medic, he is slow and completely unarmed.

After the war, they were relieved of duty as, starting with the Third World War, engineers can enter an IFV, turning it into a sort of a repair tank that can repair vehicles on the field without requiring them to return to base.
Perhaps in a strange twist of fate, the most commonly occurring trait among the mechanic corps in the height of their operations was a distinct southern American accent. It seemed to many commanders as if all mechanics were drawn from some group of like minded, automobile-proficient masters of their tools.
