 The hum of motors and the sounds of marine storming beaches filled the air as Marines practiced amphibious assaults. Having the capability of coming in through the water and then leaving the same way without being captured or caught or even seen is definitely an important role. This training is used to teach Marines how to take beaches and provide surveillance during wartime operations. We'd actually use this if we were to get into any sort of war or anything like that, that we need to get surveillance on any type of beaches. The most important thing that we're learning today is the proper way to actually infiltrate and land on the beaches without being detected. The Third Intelligence Battalion's mission is to collect, process, produce and disseminate intelligence for three Marine Expeditionary Forces command element. Reporting from Okinawa, Japan, I'm Marine Corporal Jonathan Pearson.
