The largest segment of Veterans in the USA is Vietnam Veterans.
Current Veterans are either:
a) WWII Veterans
b) Korean War
c) Vietnam War
d) Gulf War Pre 9/11
e) Gulf War Post 9/11
I don’t know what f) will be. But this is the list for now. Some are Veterans by choice and some are Veterans by conscription. I don’t know what it is called if one has served but not in any of these wars. They are Veterans too but I don’t know how they are counted.
Today is Veterans Day in the USA
