Sea Lines of Communication are major maritime routes between ports around the world and are used for trade, military/naval, logistics and other purposes.
SLOCs, or Sea Lines of Communication, function as commercial trade routes in peacetime, but during wartime, they acquire a strategic place. The party that controls them has the upper hand, as seen in many historic naval battles.
SLOCs are also strategic waterways vital for nations to access resources in faraway regions. Hence, protecting the sea lines of communication becomes essential for the free flow of global maritime trade.
