Which NSWG is tasked with undersea special operations?

The correct choice, NSWG 3, is specifically designated for undersea special operations within the Navy Special Warfare Group framework. This group specializes in a range of missions that take place in the undersea environment, employing a variety of tactics and capabilities to accomplish its objectives. The focus of NSWG 3 includes operations such as maritime reconnaissance, direct action, and unconventional warfare, which often require specialized training and equipment suited for underwater activities.

Each of the other Navy Special Warfare Groups has distinct missions that cater to land and maritime operations in different contexts. For instance, NSWG 1 primarily focuses on operations in the Pacific and is involved in direct action missions and reconnaissance on land and sea. NSWG 2, on the other hand, operates in the Atlantic, conducting similar missions but with regional differences based on strategic needs. NSWG 4 is focused on supporting the Navy’s efforts with capabilities related to intelligence, surveillance, and reconnaissance, but does not specialize in undersea operations. Thus, NSWG 3's unique mission competency makes it the correct answer for the task of undersea special operations.
