Which type of documentation is not typically included in "in-country" Vietnam service records?

The inclusion of medical treatment reports in "in-country" Vietnam service records is not typical because these records primarily focus on documenting a serviceman's assignment and experiences while in Vietnam, rather than detailed health-related information. Medical treatment reports generally fall under different types of documentation that might be stored separately, often managed by medical facilities or health records departments.

On the other hand, DD-214 documentation is a key document summarizing a veteran's service and is commonly included in service records. Copies of military orders provide specific information about the assigned duties and locations, and buddies’ statements often offer personal accounts of experiences during service. These types of documents are more relevant to understanding an individual's service in Vietnam and are likely to be found in those records.
