Laser Destroyer

Lokk drove by neural linkage. In Legion days the tank had required a crew of three. Now, he alone was sufficient to man it and fire its weapon. The malevolent spirit that dwelled in Dracokravgi’s systems, a gift from the gods for his devotion, helped with other tasks. The laser destroyer never failed. Its power couplings never needed replacing. Dracokravgi was loyal and fierce. He thanked Kar-Gatharr for that.

	The battle cannon shell was preceded by a sudden surge of power readings across Lokk’s auto-senses, and yet he had no time to react. The shot would have blasted open a ferrocrete bunker. Against Dracokravgi’s armour, it barely made a dent, glancing off the glacis and caroming upwards into a twisted spar. The shell blew, fire billowed over him.
...
	Lokk lined up for the killing shot. The Leman Russ was doomed. A single shot would core the thing through and slaughter the crew.
