"Despite its sobering focus, this museum that looks at the devastating effects of the Vietnam War—known locally as the American War—is very popular. Displays of military equipment and defused ordnance outside the main building are reminders of the huge number of weapons employed during the conflict; they also prime visitors for the powerful exhibits inside. The most disturbing of these are the many graphic photos displayed in galleries that highlight seminal moments of those years (including the infamous My Lai Massacre) and the catastrophic effects of the chemical weapons that were used against the Vietnamese."
