Some GI volunteered to go to Vietnam. But many of the soldiers who went were drafted into the service, ineligible for a student deferment because they had never been to college.
They had to deal with several frustrations particular to the war in Vietnam. Many were brought in piecemeal as replacements within existing units, which made them feel disconnected from the larger group. And with no geographical lines separating friend from foe, the GI in the field couldn't trust anyone. Villagers might be innocent civilians or Viet Cong sympathizers.
The majority of American soldiers never witnessed large-scale battles or suffered through the terror of a jungle ambush during their one-year tours. But when they did, dozens of men could die within minutes. If they are lucky enough to survive the year until his Date Eligible for Return from Overseas, or DEROS, they get to go back home in one piece.
Hope it helps
cheers
