Plehn, military deputy commander, U.S. Southern Command, speaks during the closing ceremony for the hospital ship USNS Comfort (T-AH20)’s eight-day medical mission in St. George's, Grenada, Sept. 20, 2019. Comfort is working with health and government partners in Central America, South America, and the Caribbean to provide care on the ship and at land-based medical sites, helping to relive pressure on national healthcare systems, including those strained by an increase in cross-border migrants.
