Navy OCS Division Officer (DIVO) Practice Test

A maritime chokepoint is a narrow passage that connects two larger bodies of water, concentrating ship traffic through a small, restricted area and making the route pivotal for global navigation. Because the channel is narrow, even small disruptions—weather, accidents, or congestion—can cause outsized delays and affect supply lines. The statement that best fits this idea describes a narrow stretch of water linking two major bodies of water, capturing both the constricted geography and its strategic importance. The other descriptions don’t fit: a wide expanse with heavy traffic isn’t constraining, a port facility is a location for loading or unloading rather than a natural choke point, and naval treaties about straits are legal instruments, not physical passages.
