Wu Yu-wei, 26, cries as two fellow ARP trainees leave the program during the last week of a ten week program to become a member of the Taiwan navy's elite Amphibious Reconnaissance and Patrol unit, at Zuoying navy base, Kaohsiung, southern Taiwan, December 19, 2021. Wu said he considered it a "personal challenge" to complete the course. "The first few days are exhausting, and then you get used to it. You have to rely on your willpower and determination."
