West Coast-based Naval Special Warfare (NSW) operators conduct military dive operations and prepare to board the Los Angeles-class fast-attack submarine USS Greeneville (SSN 772).Petty Officer 1st Class Alex SmedegardThe Naval Special Warfare community's role could be expanded in a conflict with China or Russia.Navy SEALs recently trained alongside the submarine USS Greenville in the Pacific.This type of training reflects efforts to prepare for a higher-end fight, in which waters may be highly contested.In the event of a conflict with China or Russia, the Naval Special Warfare community is expected to have an even larger role than it had during the counterterrorism and counterinsurgency campaigns of the Global War on Terror (GWOT).With the majority of the world covered by water, including oceans, lakes, and rivers, Navy SEALs and Special Warfare Combatant-Craft Crewmen (SWCC) operators are expected to be at the tip of the spear of the special operations community in a potential conflict with Beijing or Moscow.This community, however, will need to operate with conventional forces, such as submarine crews.Earlier in the summer, Navy SEALs assigned to West Coast SEAL Teams worked with the Los Angeles-class attack submarine USS Greeneville in fleet interoperability training to boost their ability to fight together in the maritime domain.The SEALs flew in close to the submarine's position before conducting a military freefall parachute jump.
