PBR (Patrol Boat, River)

Patrol Boat, River (PBR) refers to a type of fast, agile patrol boat used by the U.S. Navy, particularly during the Vietnam War. Designed for shallow waterways, these boats were equipped with powerful engines and armed with machine guns and grenade launchers. PBRs were crucial for monitoring river traffic, conducting reconnaissance, and engaging enemy forces in rivers and coastal areas. Their ability to operate in shallow and challenging environments allowed them to support ground troops and enforce maritime security, making them vital assets in asymmetrical warfare situations.
