What military capacity does the Coast Guard possess under its authorities?

The Coast Guard possesses the authority to make warrantless arrests ashore, which is an important aspect of its law enforcement responsibilities. This capability allows Coast Guard personnel to enforce federal laws related to maritime and fisheries regulations, as well as to maintain safety and security in navigable waters. Their jurisdiction extends not only to the ocean but also to the adjacent land areas, particularly in situations where maritime law enforcement is necessary.

This authority is derived from the Coast Guard’s dual role as both a federal law enforcement agency and a military service, enabling it to operate effectively in a variety of environments. The ability to make warrantless arrests is crucial for the Coast Guard to respond swiftly to crimes such as smuggling or illegal fishing activities and to ensure compliance with various laws intended to protect both marine resources and national security.

The other options represent capacities that do not accurately reflect the Coast Guard's mission and authorities. For instance, tactical airstrikes fall primarily within the purview of the military branches, while logistical support to the Navy, despite being an inter-service cooperation possibility, is not a primary role of the Coast Guard. Furthermore, control over international maritime law enforcement involves complex diplomatic relations and global treaties, which primarily engage international entities rather than singular authority by the Coast Guard.
