If you are scheduled to attend CBRN Basic Officer Leaders Course (CBOLC), you will receive a email from the your instructor in the Officer Training Department (OTD) with specific reporting time and location. The information below provides a general overview of the course and corresponding expectations.

Course Overview:

CBOLC is a 17-week course, which provides CBRN Lieutenants the technical and tactical skills and knowledge to perform the duties and responsibilities required of platoon leaders and battalion level CBRN officers. This instruction is both externally and internally directed and includes Chemical, Biological, Radiological, Nuclear and HAZMAT operations, as well as combined arms operations.

Each course typically consists of 45-50 students, typically: 48 Army officers and 2 Coalition Partners from areas as diverse as Europe, the Middle East, and Asia.

The training days are typically 8-12 hours daily. Instruction is primarily classroom-based, either in large class room format, or in small-group discussion. Extensive emphasis is placed on group practical exercises, prior military experience and computer simulations. Additionally, training will also be conducted in the field environment.

Classes conduct physical training five days per week, at a minimum. It is extremely important to report for the course in shape. During the first week of the course, students will be weighed/taped to ensure compliance with the Army’s Body Composition Standards IAW AR 600-9 as well as take the diagnostic Army Physical Fitness Test (APFT). There are a total of two diagnostic APFTs and one final record APFT. Finally, students will be weighed/taped to ensure compliance with the Army’s Body Composition Standards IAW AR 600-9 prior to each APFT. Clickherefor a Road Guard Vest example.
