Port Security Units
Port Security Units (PSUs) are specialized teams within the U.S. Coast Guard responsible for safeguarding maritime ports and harbors. They operate around the clock to prevent terrorist attacks, smuggling, and other threats by monitoring access points, inspecting vessels, and coordinating with other security agencies. PSUs use advanced technology, patrol boats, and trained personnel to ensure the safety of critical maritime infrastructure, cargo, and personnel. Their role is essential in maintaining national security and facilitating the smooth flow of commerce through safe, secure ports.
