What is the difference between a Vietnam Veteran to a World War 2 Veteran?

Vietnam War veterans are members of the military (of any country) who have served during the Vietnam war (1959-1975) -- while World War 2 veterans served during WWII (1939-1945). I have several family members who have served in both wars. You can learn about some of the symbols/conflicts/awards during both wars at SoldierCity. They have a large assortment of medals, patches, and flags for both wars. In fact, I just went to www.soldiercity.com to get a Vietnam flag for my grandfather (a Vietnam War veteran), and some World War 2 clothing w/Navy ships for his dad (one of our highly honored WWII veterans, who's alive and well to this day!)
