Some Vietnam statistics I can never seem to get a handle on...

[MORTARDUDE]

I have pondered for some time how many "unique individuals" from the US military actually set foot in Cambodia, Laos, and South and North Vietnam from 1959 - 1975...
I have seen numbers all the way from 2.2 million to 5+ million...
I have also tried to determine how many "unique individuals" actually set foot on these 3 countries in that time period and were only in the 11B and 11C MOS...It is a hell of a lot harder than you might imagine...If you take the average strength of an infantry division...well it can vary from as low as 40% to 85% at any given period of time...people were rotating in and out from all over and changing MOS....Bottom line is that no one seems to know...is there a list somewhere that breaks all the folks on the Wall down by branch of service and within each by MOS ? I have never understood why the stats on the Wall never seem to include the Infantry Division involved down to the Company level for the dead. Seems like that would have been one of the first things recorded....Just one of life's little conundrums..I suppose.
