OXON HILL, Md. (AP) -- The commandant of the Marine Corps, General James Amos, is among the speakers at a National Harbor trade show billed as the largest maritime exposition in North America.
The Navy League Sea-Air-Space expo begins Monday at the Gaylord National Resort and Convention Center and continues through Wednesday.
Amos is on a panel that includes Coast Guard commandant Admiral Robert Papp and Navy chief of naval operations Admiral Jonathan Greenert. They'll be providing updates on their service branches.

The expo features 180 exhibitors, including 18 military commands, displaying some of their latest technologies, activities, produces and services.
