Between 1965-1970, 26 82' cutters were deployed into naval use and painted gray to support which war?

The deployment of the 82-foot cutters painted gray during the period from 1965 to 1970 was specifically in support of the Vietnam War. During this conflict, there was a significant need for coastal patrol and support operations in Vietnam, as well as for military engagement along the Mekong River. The U.S. Coast Guard adapted these vessels for naval operations, enhancing their visibility and ability to integrate into the naval fleet by painting them gray.

The other conflicts mentioned—the Gulf War, the Korean War, and World War II—occurred at different times and under different circumstances where such a deployment of these particular cutters was not relevant. For example, the Gulf War happened in the early 1990s and did not involve the same types of vessels, while the Korean War and World War II occurred before the introduction of the 82-foot cutters into service. This contextual backdrop underscores why the Vietnam War is the correct answer regarding the deployment of these cutters.
