Often, they carried each other

"Some things they carried in common. Taking turns, they carried the big PRC-77 scrambler radio, which weighed 30 pounds with its battery. They shared the weight of memory. They took up what others could no longer bear. Often, they carried each other, the wounded or weak. They carried infections. They carried chess sets, basketballs, Vietnamese-English dictionaries, insignia of rank, Bronze Stars and Purple Hearts, plastic cards imprinted with the Code of Conduct. They carried diseases, among them malaria and dysentery. They carried lice and ringworm and leeches and paddy algae and various rots and molds. They carried the land itself—Vietnam, the place, the soil—a powdery orange-red dust that covered their boots and fatigues and faces. They carried the sky. The whole atmosphere, they carried it, the humidity, the monsoons, the stink of fungus and decay, all of it, they carried gravity. They moved like mules. By daylight they took sniper fire, at night they were mortared, but it was not battle, it was just the endless march, village to village, without purpose, nothing won or lost."

~Tim O’Brien, The Things They Carried, 1990
