Tales from New Terra
Penny Hill sighed as she entered the Garage. Sometime during the night, there had been a war. It was obvious enough why Tolo had called her in four hours before her regular shift. Every bay was full, the Robot Assist Mechanics busy in every one, and on three of the bays the yellow lights flashed, indicating that human assistance was needed. Worse than that, on the way in she'd seen the line of vehicles waiting outside, running all the way around the building.
Before zeroing in on any one of them, she waved at Tolo as he poked his head out of a Tiger's EMP turret, and made the rounds of the building. Most of the damaged vehicles were combat units, carrying a full menu of battle damage: Laser damage, acid burns, craters from Rail Gun projectiles, EMP-fried electrical systems, and the characteristic jagged cuts created by the Thor's Hammer weapon.
Finally she turned her attention to an EMP Panther, so pitted and scarred by acid its armor looked little thicker than tissue paper. Perhaps she could write it off as a total loss and open the bay up for a more readily repairable unit.
As she climbed up its scarred flank, she sighed. Whoever said that automated combat didn't produce casualties wasn't a mechanic.
