AFSWP was given responsibility for discharging all military functions relating to atomic energy in coordination with the Atomic Energy Commission. General Groves was placed in charge, and reported directly to the Joint Chiefs of Staff. Concerned about the postwar status of the nation's nuclear stockpile, Groves had already dispatched Col. Gilbert M. Dorland to Sandia Base to evaluate the engineering efforts being made there. Dorland eventually assembled a group of about sixty young Army officers, later nicknamed the "Sandia Pioneers," to oversee the bomb fabrication efforts. Dorland also established a nuclear weapons training school at Sandia Base.
