In groups of four or five, the men walked 29.5 feet until they reached a barbed wire wall. Passing underneath it, they continued to crawl under nearly 50 feet of low barbed wire. This obstacle cleared, they sprinted 20 feet and dove into a foxhole where they hid from an absent enemy for ten seconds. Once the ten second had passed, they leapt from the foxhole and sprinted 26 feet to another barrier under which the had to crawl. This barrier cleared, they sprinted the final 50 feet to a wall made of smooth wires at which point they lobbed two practice grenades into a 4 square foot pit 36 feet away. Their grenades thrown, each man finished the course by giving his name to the test supervisor.
