high explosive rounds

Bunny knelt beside a tree, aimed, and fired, but his shot went high and hit the top of the crate instead of one of the Fixers. The explosion blew off one side of the huge wooden box, and the fighting machine inside toppled out. The four men scattered, but one was half a step too slow, and the K-110 smashed down on his rear leg. He collapsed screaming. The other men snuck under the truck and squirmed up and out again with the fallen machine as cover. Bunny saw a glint of metal and glass as the access hatch opened and a Fixer wriggled inside. He fired at the cowling, but even though he scored a direct hit, the K-110 hummed to life.

The ungainly device got to its feet, and the driver brought the gun arms up. Bunny hit it again and again with high-explosive rounds, but if it did any damage, he couldn’t see it.
