Headquarters, Department of the Army Foreword As the chemical Corps enters its second century of service in the United States Army, it must adapt to new threats and overcome 15 years of atrophy of chemical , biological , radiological , and nuclear (CBRN) skills within the Army that were attributed to operations in counterinsurgency. Throughout that time, the chemical Corps approached the CBRN problem as it had for the past 100 years avoid, protect, and decontaminate.

2 These three insular capability areas provided a linear approach to detect existing hazards and offered a bypass of CBRN. obstacles to enable the safe passage of forces. The approach to the CBRN program remained slow to change, discounting new forms of battle being exercised and conducted by major regional players (Russia, China, Iran, and North Korea). The proliferation of new technologies, to include weapons of mass destruction (WMD). capabilities and materials, will remain a constant during the next 100 years.

3 The chemical Corps, in conjunction with the Army and joint force, must adapt and prepare for CBRN usage throughout the range of military operations . The chemical Corps exists to enable movement and maneuver to conduct large-scale ground combat operations in a CBRN environment. Friendly forces must retain freedom of action and be capable of employing the full breadth of capabilities within complex battlefield conditions, including CBRN environments. The latest addition of FM 3-11 ( chemical , biological , radiological , and nuclear operations ) outlines the core functions of Assess, Protect, and Mitigation with the integrating function of Hazard Awareness and Understanding to defeat pacing threats and near-peer adversaries in a contested CBRN environment.

4 ATP CBRN Platoons is a complementary publication that addresses tactical operations from a CBRN platoon perspective in support of decisive action. To support large-scale ground combat operations , the Army CBRN Regiment's platoons must be agile and adaptive, capable of employing their full capabilities to enable the Army to win in a complex CBRN environment. It is essential that CBRN platoons maintain operational readiness and CBRN mastery while supporting freedom of action for maneuver units. CBRN platoons must be integrated throughout tactical formations as a critical enabler to maintain overmatch in contested CBRN environments where adversaries will leverage weapons of mass destruction to establish and maintain a position of relative advantage.

5 ATP provides a thorough doctrinal approach for CBRN platoons at the tactical level of war to provide options for maneuver commanders. Most importantly, it provides CBRN company and platoon leadership doctrinal guidance to employ offensive and proactive CBRN capabilities to maintain force overmatch against our adversaries. Our CBRN platoons deserve the very best in agile and adaptive leadership that can support the friendly scheme of maneuver within the complex rigors of CBRN environments. ATP CBRN Platoons provides CBRN.
