On August 10, 1990, Congress passed U.S. Public Law 101-355, which recognized the Prisoner of War/Missing in Action flag and designated it “as the symbol of our nation’s concern and commitment to… fates of Americans still prisoner, missing and unaccounted for.” Each year, the flag is flown on Armed Forces Day, Memorial Day, Flag Day, Independence Day, National POW/MIA Recognition Day and Veterans Day.
