Mellas stood beneath the gray monsoon clouds on the narrow strip of cleared ground between the edge of the jungle and the relative safety of the perimeter wire. He tried to focus on counting the other thirteen Marines of the patrol as they emerged single file from the jungle, but exhaustion made focusing difficult. He also tried, unsuccessfully, to shut out the smell of the shit, which sloshed in the water that half-filled the open latrine pits above him on the other side of the wire. Rain dropped from the lip of his helmet, fell past his eyes, and spattered onto the satiny olive cloth that held the armor plating of his cumbersome new flak jacket. The dark green T-shirt and boxer shorts that his mother had dyed for him just three weeks ago clung to his skin, heavy and clammy beneath his camouflage utility jacket and trousers. He knew there would be leeches clinging to his legs, arms, back, and chest beneath his wet clothes, even though he couldn't feel them now. It was the way with leeches, he mused. They were so small and thin before they started sucking your blood that you rarely felt them unless they fell on you from a tree, and you never felt them piercing your skin. There was some sort of natural anesthetic in their saliva. You would discover them later, swollen with blood, sticking out from your skin like little pregnant bellies.
