The Official U.S. Army Chemical, Biological, Radiological, and Nuclear Operations Field Manual is the newest edition of this critical U.S. Army field manual about the nuclear, chemical, and biological threats to our military members and civilians and covering a soldier's or anyone's - use of protective gear and equipment to make himself and herself and their families safe. The United States Army must adapt to new threats and overcome 15 years of atrophy of chemical, biological, radiological, and nuclear skills within the Army due to a focus in recent years on operations in counterinsurgency. During this time, it ignored new forms of battle being exercised and conducted by major regional players such as 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 coming years. The Army and joint forces MUST adapt and prepare for the use of these new technologies. Civilians must prepare, too. The Official U.S. Army Chemical, Biological, Radiological, and Nuclear Operations Field Manual is must-reading.
