Between a ROZ and an AC, which is more restrictive and why?

The correct answer is based on the characteristics of a Restricted Operations Zone (ROZ) and an Airspace Coordination Area (AC). A ROZ is specifically designed to limit or restrict operations within a defined airspace to protect friendly forces or areas. It is often employed to enhance safety and minimize the risk of friendly fire by clearly delineating areas where certain operations are prohibited, ensuring that the space is controlled to avoid unintended interactions.

In contrast, an AC provides guidance on the coordination of airspace use among different units, focusing more on coordination and deconfliction rather than outright restriction. While an AC can certainly involve altitude restrictions, its primary purpose is to facilitate the effective use of airspace rather than to impose limitations.

Thus, a ROZ is considered more restrictive than an AC because it directly limits activities within its airspace and encompasses a greater area intended for specific tactical purposes on the battlefield. This containment approach allows for a clearer operational focus and helps ensure the safety of forces under its protection, making it inherently more restrictive in nature compared to the more flexible nature of an Airspace Coordination Area.
