Have a look at this web site it seems that DH&H are in charge but turn the responsibility over to the Base Commander who can set the priorities and do as he pleases. Kind of reminds you of all those paintings from the CWM that went astray. I wonder if some retired general will end up with a tank on his front lawn?
