Anti-Access/Area Denial (A2/AD) refers to military strategies designed to prevent an adversary from entering a specific area or accessing certain resources. This approach often involves a combination of advanced technologies, such as missiles, radar systems, and naval assets, to create a protective barrier around a region. The goal is to deter or delay enemy forces from operating effectively within that space. Countries like China and Russia have developed A2/AD capabilities to safeguard their territorial interests and influence regional dynamics. By establishing these defensive measures, they aim to complicate the operational plans of potential adversaries, thereby enhancing their own security and strategic advantages.
