PHILIPPINE SEA (Feb. 27, 2021) A U.S. Navy Mark VI patrol boat with Maritime Expeditionary Security Squadron Two moves through the water prior to a live fire exercise in the Philippine Sea, Feb. 27, 2021. The exercise was conducted to test the effectiveness of firing various weapon systems at sea from smaller, more expeditionary platforms than are traditionally used. The 31st Marine Expeditionary Unit is operating aboard ships of the Amphibious Squadron 11 in the 7th Fleet area of operations to enhance interoperability with allies and partners and serve as a ready response force to defend peace and stability in the Indo-Pacific region.
