the academy on Reception Day or R-day, which marks the start of cadet basic training (CBT), known colloquially as Beast Barracks, or simply Beast. Most cadets consider Beast to be their most difficult time at the academy because of the transition from civilian to military life. Their second summer, cadets undergo cadet field training (CFT) at nearby Camp Buckner, where they train in more advanced field craft and military skills. During a cadet's third summer, they may serve as instructors for CBT or CFT. Rising Firstie (senior) cadets also spend one-month training at Camp Buckner, where they train for modern tactical situations that they will soon face as new platoon leaders. Cadets also have the opportunity during their second, third and fourth summers to serve in active army units and military schools around the world. The schools include Airborne, Air Assault, Sapper, Pathfinder, etc. Active duty officers in the rank of captain or major serve as Company Tactical Officers (TAC Officers). The role of the TAC is to mentor, train, and teach the cadets proper standards of good order and discipline and be a good role model. There is one TAC for every cadet company. There is also one senior Non-Commissioned Officer to assist each TAC, known as TAC-NCOs. The Department of Military Instruction (DMI) is responsible for all military arts and sciences education as well as planning and executing the cadet summer training. Within DMI there is a representative from each of the Army's branches. These "branch reps" serve as proponents for their respective branches and liaise with cadets as they prepare for branch selection and graduation. Within DMI sits the Modern War Institute, a research center devoted to the study of contemporary conflict and the evolving character of war. Physical The Department of Physical Education (DPE) administers the physical program, which includes both physical education classes, physical fitness testing, and competitive athletics. The head of DPE holds the title of Master of the Sword, dating back to the 19th century when DPE taught swordsmanship as part of the curriculum. All cadets take a prescribed series of physical fitness courses such as military movement (applied gymnastics), boxing, survival swimming, and beginning in 2009, advanced combatives. Cadets can also take elective physical activity classes such as scuba, rock climbing, and aerobic fitness. As with all soldiers in the Army, cadets also must pass the Army Physical Fitness Test twice per
