The POW/MIA flag was first recognized on August 10, 1990.
In the United States, National POW/MIA Recognition Day
is observed on the third Friday in September.
It honors those who were prisoners of war (POWs) and
those who are still missing in action (MIA).
It is most associated with those who were POWs during
the Vietnam War.
National Vietnam War Veterans Day is March 29, the date
in 1973 when the last US combat troops departed the
Republic of Vietnam.
