U.S. Marine Capt. David Washburn, a CH-53E Super Stallion helicopter pilot with Special Purpose Marine Air-Ground Task Force - Southern Command, speaks with a Brazilian Naval Infantry tactical air controller during a planning team meeting as part of UNITAS Amphibious in Rio de Janeiro, Aug. 22, 2018. The knowledge gained and procedures put in place during this year’s tabletop exercise will inform the UNITAS Amphibious field training exercise in 2019. The intent for next year’s live event is to embark participating partners at sea. This will serve as a proof of concept for establishing interoperability amongst the region’s navies – and ultimately the development of a standing multinational maritime task force postured to respond to humanitarian assistance and disaster relief situations throughout the region.
