• B. Allied Access/Defense
• C. Air to Air Denial
• D. Autonomous Defense

Answer: (A)

A2/AD stands for Anti-Access/Area Denial, a concept describing strategies to deter or complicate an adversary’s ability to operate near or within a theater of operations. In military modernization, this means building a layered system of weapons, sensors, and networks designed to prevent enemies from entering a region (anti-access) and, if they do get inside, to make their freedom of action within that space costly and risky (area denial). For China, that includes long-range missiles, advanced air and missile defense, submarines, maritime surveillance, space and cyber capabilities, and integrated command-and-control, all aimed at complicating U.S. and allied power projection in the region. The goal is to raise the perceived risk and cost of intervention, thereby shaping deterrence and crisis stability. Other terms don’t capture this theater-wide, layered approach, or are not standard descriptors of the concept.
