When ever I look at two different interpretations of a story and try to figure out who is telling the truth I always ask myself who has a reason to lie? What is there to gain by not telling the truth?
I see no reason whatsoever why Ken Foose has anything to gain by making up these claims. Unfortunately the other parties in question have a lot to more on the line and have yet to explain the abrupt departure from USARK.
One party has an explanation as to the departure and the other skirts the issue which a generalized statement. I have no reason to side with anybody but this varied approach speaks volumes to me.

Food for thought.
