An ARP trainee pulls a fellow trainee, who is pretending to be injured, through sewage contaminated water during the last week of a ten week program to become members of the Taiwan navy’s elite Amphibious Reconnaissance and Patrol unit, at Zuoying navy base, Kaohsiung, southern Taiwan, December 21, 2021. The trainees have to endure everything from long marches to hours in the water, with constant screaming at by their instructors. Of the group of 31 who started the program, only 15 finished.
