Taste test
BAGRAM AIR BASE, Afghanistan -- Maj. (Dr.) Michael Paston offers a Thai ration to Staff Sgt. Brian Raphael, who sniffs it skeptically, while Senior Airman Brian Miller waits his turn. Their inputs about the ration will be recorded and used in Paston's research. Paston, Raphael and Miller are assigned to the 455th Expeditionary Operations Group here.
