Sergeant Clay signaled to clear the hatch opening. He threw the first grenade into the lizard's control room. My ears rang and the pressure wave knocked me back. Nails, screws, and broken glass tore through the confined space. Lizards screeched in pain as our shrapnel punched holes into their leathery bodies. A thick green mist of lizard blood hung in the air. Dan tossed the next grenade. More reptilian screams. More ringing in my ears. The stink of exploded lizards replaced the choking, acrid smoke from our homemade grenades. I was ready to go in. We all were. Now was the time to finish off the lizards.
