 As the USS Greenbin made port in Okinawa, Marines from the 31st Marine Expeditionary Unit prepared to board the ship for a patrol across the Indo-Asia-Pacific region. The objective of this patrol is to increase combat readiness and enhance partnerships with allies in the region through exercises and training. I've been exercising with the 31st Marine Expeditionary Unit for the last 16 years. This is my fourth tour serving out of Sasebo, Japan on amphibious ships. It is something that I hold very near and dear to my heart. It's something I'm used to, but it's also something that I still find incredibly exciting. This drive runs down the ranks to the most junior Marines and sailors on ship. I'm pretty excited about working with Navy counterparts, being on board on a flight deck with flight operations going on all around me. Reporting from White Beach Naval Facility, I'm Marine Corporal Marcella Diaz de León.
