Most law firms offer some sort of orientation and training, and the JAGC is no different. 

The Judge Advocate Officer Basic Course (JAOBC) is comprised of three phases: 

Fort Lee Phase. New JAs report to Fort Lee, Virginia, for a twelve day military orientation course, which is known as the Fort Lee phase of Judge Advocate Officer Basic Course (JAOBC). The course allows time for establishing personnel and finance records, purchasing uniforms, and receiving instruction in several basic areas of military life. These include the wear of military uniforms, military customs and courtesy, and physical fitness training. 

Charlottesville Phase. The military orientation course is followed by a ten-and-a-half week academic course at The Judge Advocate General's Legal Center and School (TJAGLCS) in Charlottesville, Virginia, which is known as the TJAGLCS phase of JAOBC. TJAGLCS is located on the grounds of the University of Virginia, adjacent to their law school. During this phase, new JAs receive instruction on the organization, function, and mission of the U.S. Army JAG Corps, and an overview of the practice of law in the U.S. Army. The instruction focuses on areas of law that will be particularly important to a new JA, including military criminal law, government contract and fiscal law, legal assistance, claims, administrative law, and international and operational law. Computer training and practical exercises in trial advocacy and attorney-client issues are also featured. 

Direct Commissioned Officer Course (DCO). The training continues with six weeks of DCO located at Fort Benning, Georgia. DCO’s goal is to develop competent leaders. It is a rigorous six-week course in leadership and tactics designed to challenge ALL new Army officers (West Point, ROTC and Officer Candidate School graduates also attend) physically and mentally. The DCO curriculum includes physical fitness training, foot marches, combat training, land navigation training (similar to orienteering), rifle marksmanship, weapons training, practical exercises in leadership, nuclear, biological and chemical operations, use of night-vision equipment and several confidence courses featuring difficult obstacles that will challenge students to overcome personal fears.
