Martin paused for a moment at the sound of the grenade going off and shrapnel pinging off the hull. No sounds of people injured, and the tone of the explosion was not one that would rend metal or otherwise damage the tank. So, that was probably not an armor piercing one, and the others up top should be able to handle it. Swiveling the gun around again, he surveyed the remaining enemy vehicles while the turret ticked back around. The platform truck would probably go down in another hit, and the harpoon truck was more or less fine. The rest were rather light for spending a round from the main cannon, even the relatively cheap shot that they were using. But having more damaged vehicles would mean either abandoning more vehicles or spending more time doing repairs. And he knew the kind of time that such repairs could require if you wanted to fix a hit from something this big. So, he tracked back to the harpoon truck, lined up his shot and called out, "Firing."
