Well, the movie '5 bloods based on a true story' centers around a group of Vietnam War veterans. While I can't name each character specifically off the top of my head, these men are united by their shared past in the war. They have a strong bond that was formed during their time in combat. Some might be more outspoken, some more reserved, but all of them are haunted by their experiences in the Vietnam War in one way or another. And as they return to Vietnam, their individual characters are further explored as they face the challenges and revelations that come with this journey.
I'm not entirely sure about all the specific names of the main characters, but they are a group of Vietnam War veterans.
