If you have the time and the interest, you should check out Ken Burns and Lynn Novik's The Vietnam War, one the best documentaries I've EVER seen.
An almost 20 hours long documentary which goes in great depth with the war itself, what caused it (the whole first episode is about the events BEFORE it) the homefront, the politcs, the protests, the daily life. Thousands of photos and footage from the era and an excellent and compelling narration.
Last but surely not least, you'll find interviews to veterans from all branches of the US armed forces, the NVA and NLF (Vietcong) and the ARVN; interviews to civilians, americans and vietnamese alike: veterans' family, students, protesters, deserters, farmers...it's from the PBS and I've seen that Netflix (at least, it Italy) had recently bought it. The versions on youtube or other channels are pirated vietnamese copies without the subtitles for the vietnamese veterans, so it's not really the best way to watch it, but if you wish so...
