Help with identification of Vietnam War-era Slides

[tfhiii]

Hello,

 

I recently came across a large collection (about 237 total) of slides from a soldier's estate. I know nothing about the soldier's service, except that he appears to have served at a helicopter base(s) in Vietnam ca. 1970. I'm hoping that someone might recognize the countryside and the type of helicopter, so I can possibly learn about his unit and location. I'll have to post additional photos separately because the file size is too large. Any help would be greatly appreciated.

Here are some additional of slides of unidentified base in Vietnam, ca. 1970.

I wonder if the symbol on this building might help. Maybe someone will recognize it. It almost looks like a diving bird or maybe a bat.

Sorry for the long-time no response. Thanks for the detailed photo aznation, very cool.
