While the POW/MIA flag “reminds us to never forget our prisoners of war and missing in action,” says Military.com, bracelets were introduced in the 1970s as a more personal form of remembrance. They are still worn by the friends and relatives of Vietnam’s 725 POWs and more than 1,600 MIAs, as well as those remembering service members imprisoned or missing in action from other wars. Voices in Vital America (VIVA) “distributed nearly 5 million bracelets during the 1960s and 1970s to draw attention to the missing men,” says POW/MIA Families, which continues its work today.
