With all due respect, I checked a number of websites on the Medal of Honor and found no GARNER listed as a recipient of the award. If you have his Medal or know who does or a copy of the Citation I suggest that someone make an effort to correct this over site.
I mean no disrespect, but I have the greatest respect for this award and for genealogy and do not wish to see incorrect information being made public. http://www.homeofheroes.com/moh/war/17_vietnam.htmlhttp://www.cmohs.org/http://en.wikipedia.org/wiki/List_of_Medal_of_Honor_recipien... http://www.history.army.mil/html/moh/vietnam-a-l.html
There is also no Ronnie/Ronald Garner listed on the Vietnam Wall so the military must have him by another name. Finding records would be easier if we knew that name. Perhaps he was a civilian working in Vietnam? http://thewall-usa.com/
