The Viet Cong used reinforced bicycles as cargo carriers. These weren’t ridden — they were pushed by hand, loaded with up to 400 pounds of supplies along the Ho Chi Minh trail. The bikes were silent, needed no fuel, and could travel narrow jungle paths where trucks couldn’t. | History Collection

U.S. soldiers tasked with entering the Viet Cong tunnels were nicknamed “tunnel rats.” They had to crawl into pitch-black, narrow passages with only a flashlight and a pistol, not knowing if they’d face traps, snakes, or an enemy waiting. Some tunnels were deliberately infested with venomous creatures to slow intruders. | History Collection
