U.S. Army Brig. Gen. Pablo Estrada, Task Force Center

U.S. Army Brig. Gen. Pablo Estrada, Task Force Center commanding general, breathes in a compound designed to leave a distinctive taste when inhaled during a procedure to appropriately fit an N95 face mask at Sanford Health Fargo, Fargo, N.D., Dec. 15, 2020. This “fit test” procedure is then repeated while Estrada wears his mask; if he doesn’t detect the compound’s taste with the mask on, it is fitted appropriately. U.S. Northern Command, through U.S. Army North, remains committed to providing flexible Department of Defense support to the Federal Emergency Management Agency in support of the whole-of-America COVID-19 response.
