Special emphasis is placed on reconnaissance and intelligence collection to identify WMD sites. The manual distinguishes between seizing WMDs, which means using force to capture them from the enemy, and securing sites so that no one manages to walk off with a nuke or a nerve-gas bomb in the confusion.
The Pentagon has just released a new manual that lays out how the United States might destroy North Korea’s nukes.Army Techniques Publication No. 3-90.40, “Combined Arms Countering Weapons of Mass Destruction,” explains U.S. doctrine for neutralizing WMDs. The guidelines focus on the nuts and bolts of counter-WMD combined-arms operations by brigade combat teams, or BCTs. In other words, how regular Army combat brigades should deal with nuclear, biological or chemical weapon
Though the manual doesn’t specifically mention North Korea, many of its recommendations would apply should large formations of U.S. ground troops enter North Korea. Regardless of whether the goal is regime change, a punitive incursion or destroying WMDs, it is quite possible that American troops would encounter production, storage or launch facilities for weapons of mass destruction.
