Analysis of information sources in references of the Wikipedia article "Mark V Special Operations Craft" in English language version.
The Mark V series of boats is utilized primarily by the United States Navy SEALs for high-speed insertion and extraction.
To protect the Seals, four Mark-5 jet-powered patrol boats, each armed with four twin-barreled 50-caliber machine guns, were stationed around the oil terminals like sentries. Navy snipers were also placed inside helicopters overhead.
