Who are the Special Warfare Combatant-craft Crewmen (SWCC's)? From my experience, I can say they are world class gentlemen. The U.S. Navy SWCC Information website has this to say:

Special Warfare Combatant-craft Crewmen (SWCC) operate and maintain the inventory of state-of-the-art, high-performance boats used to support SEALs and special operations missions. Individually, SEALs and SWCC go through separate, but similar, specialized training programs that emphasize special operations in the maritime environment. SWCC are trained extensively in craft and weapons tactics, techniques and procedures. Focusin on clandestine infiltration and exfiltration of SEALs and other special operations forces, SWCC provide dedicated, rapid mobility in shallow water areas where larger ships cannot operate. Like SEALs, SWCC must be physically fit, highly motivated, combat-focused and responsive in high stress situations.

Naval Special Warfare has played a significant role in Operation Iraqi Freedom, employing the largest number of SEALs and SWCC in its history. NSW forces were instrumental in the success of initial special reconnaissance and direct action missions including the securing of the southern oil infrastructures of the Al Faw peninsula and the off-shore gas and oil terminals; the clearing of the Khor Al Abdullah and Khor Az Zubayar waterways that enabled the first humanitarian aid to be delivered to the vital port city of Umm Qasr; reconnaissance of the Shat Al Arab waterway; capture of high value targets, raids on suspected chemical, biological and radiological sites; and the first successful POW rescue since WWII. NSW forces continue to conduct direct action, special reconnaissance and over watch missions throughout Iraq in support of Operation Iraqi Freedom. They established a Foreign Internal Defense program, training and advising Iraqi Forces and have worked jointly with 3rd Group USSF and Iraqi counter-terrorist forces to prevent terrorists from conducting activities meant to disrupt Iraqi elections.
