I am trying to locate a 1966-1967 site/postal/location map(s) of the
U.S. Army's Long Binh Post (installation) in Vietnam at that time,
which IDENTIFIES the SPECIFIC site location of each unit on that post.
Who in the Army, Defense Department, or other Agency has it?  ***
Note: I have, via the Internet, obtained a xerox copy of a black/white
site map of Long Binh from the Library of Congress (that shows ALL
structures/tents), but apart from the hospital, jail, and ammunition
depot, it DOES NOT identify which units were in what building/tent
structures. In October of 1966 I was lightly wounded inside the Long
Binh Ammunition Depot when the enemy succeeded in blowing up some
ammunition pads, and I was treated at the infirmary of another Army
unit directly across Highway 15 from the Ammunition Depot's main
gates. I can narrow that location (on the Library of Congress's Long
Binh map) down to 2 small groups of buildings, which probably will
turn out to be either a single Army unit or two. Once I can determine
the unit's name (e.g. 54th Ordance Company, 145th Engineer Battalion,
etc), I can then move to the next step of locating that unit's
archived medical field records for a search of my medical treatment
that October night in 1966. I have not been able to find any such map
or reference to same on the web, or any of the Vietnam books (i.e.,
Orders of Battle) referenced by the web or the Library of Congress.
The Army or Defense Department must have such maps from then either
archived or for study/research today. But I have no idea where to even
begin. I also got nowhere by researching the US Postal Service site.
Even in war zones, the Army documents and knows precisely where each
unit is located within each base camp or other installation, right
down to the "company" and "detachment" size...this, for operational
purposes, mail, supplies, command, etc. They plot this all out on site
installation maps or drawings. And they do not throw any records away.
So again: Who has this map so that I can view it or purchase a copy?
IT MUST SHOW WHAT UNITS ARE LOCATED WHERE WITHIN THE LONG BINH BASE
CAMP (aka Post, Garrison, Military Installation) perimeter, preferably
during the October 1966 period. Your assistance will be much
appreciated. Thank you.

As I understand it, you are looking for medical records that
apparently can't be found by a direct request for them:

I trust that you have exhausted this possibility

RE: myoarin-ga Comment:  Yes, my end goal is to locate a "field"
medical record that will be with the infirmary of whatever unit it was
that gave me treatment during that incident. It was NOT my own unit,
which was a mile or two away, nor was it a medical evacuation
hospital. Therefore, that record is not/would not be in my military
files at the St. Louis Records Center. I checked. It will be with the
field infirmary records of that unknown unit that treated me. I can
locate the structures on a site map of Long Binh Post, but that map
does NOT identify what unit(s) are in those structures. Thus my
question NOW is, who has, or where do I go, to get such a map of Long
Binh that identifies what units are in what buildings or tents. THEN,
yes, once the unit is identified, I can begin the process to track
down that unit's archived field medical records. Thanks for the
comment; I will check both sites you listed, but unless all field
records from all individual units in Vietnam have since been
digitized, and I am able to locate them by my name, it won't help
until I learn the name of the unit that treated me. Since it was
directly across from the Long Binh Ammunition Depot's entrances, it
likely will be a support unit of some type, such as a maintenance,
ordance, engineer, MP, or transportation company, battalion, brigade,
or detachment. Thanks again for the input. lookingglass-ga
