Which of the following best describes the central idea of conventional-nuclear integration (CNI) from the CSAF's "Capstone Concept for Conventional-Nuclear Integration?" Group of answer choices CNI is the operational concept that takes nuclear launch authority from National Command Authority and pushes it down to the operational and tactical levels. CNI is the principle that the Joint Force must be able to command and control both conventional and nuclear operations at the theater and tactical levels. CNI is the ability of the Joint Force to survive the use of nuclear weapons, reconstitute critical capabilities, plan and execute integrated conventional and nuclear combat operations, all in the midst of a nuclear environment. CNI is primarily focused on ensuring all Airmen are trained on the equipment necessary to operate in a nuclear-contaminated environment
