Course Overview:

CBRNC3 is a 22-week course, which provides company grade CBRN Officers the technical skills and knowledge to perform the duties and responsibilities required of company commanders and brigade level battle staff CBRN Officers. This instruction is both externally and internally directed; and includes chemical, biological, radiological, and nuclear operations, as well as combined arms operations. This course will dive extensively into current Army and CBRN Doctrine. If you are not familiar or out of practice you can read current doctrine at The Army Publishing Directorate or go to the Chemical Knowledge Network (CKN).

Course completion is required for branch qualification. Each course normally consists of 25-30 students, typically: 20 Army Officers; 2 USMC Warrant Officers; and 5 Coalition Partners from areas as diverse as Europe, the Middle East, and Southeast Asia. The training days are typically 0800-1700 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 class participation.

Classes conduct physical training five days per week starting at 0530. It is extremely important to report for the course in shape. On the first day of class students will be weighed/taped to ensure compliance with AR 600-9, Height/Weight standards. Additionally, an Army Physical Fitness Test (APFT) will be administered within the first 72 hours of the class. Students are required to bring a copy of their orders and, if needed, a copy of their permanent profile to day one of class.
