What were some of the negative effects of the vietnam war on America and American citizen

It is my English Composition class research paper. The paper should follow this structure and be 5 Pages (The main idea Must have 2 subdivision at least and one of subdivision must have 2 reasons or examples at least).
I. First main idea
A. First subdivision of the main idea
1. First reason or example
2. Second reason or example
a. First supporting detail
b. Second supporting detail
You should find 3 or 4 main ideas for the body (3 main idea is fine). I want you to write about Vietnam war veteran’s health problem (mental and health problem) for one of the body.
If you have any question, please let me know.
A professor is really particular about it.
when you paraphrase or quote directly could you write where is it? For example, the first page first quotation came from which page of sources. The professor needs me to copy of sources and highlighted where did I use the sentence in the research paper- Just write on the last page. It is for me. I want you to use a free source. if you really need to use not free sources, just choose 3 sources. I don’t have enough money.
