The bedrock of every resilient service member is the support of their family and friends. We were honored to recently bring our loved ones together, offering a unique glimpse into what we do every day. This special occasion included wonderful food, exciting activities, and the rare chance for our Sailors to share their experiences with their families while underway.

GM2 Chambers made the most of this rare opportunity, choosing to reenlist while underway with his family in the “gun tub” of one of our 40-foot patrol boats.

We express our heartfelt appreciation to everyone who contributed to this memorable event!
