The people at the Joint POW/MIA Accounting Command do some wonderful work but the numbers are staggering and it seems impossible to ever reach a conclusion for everyone, though, each singe identification is very important.

My brother lived next to the CO of JPAC for a while. Admirable mission they have. I've worked with them on occasion, and I have nothing but good things to say about what they do, the dedication they have doing it, and the respect they hold for their own duties and responsibilities. My work was very limited historical research with them, but some of my Vietnamese linguist buddies have worked with them more often and say the same things about them.
