Anyone interested in more detail than contained in this report is referred to the histories of the Task Group and of its units. Although Headquarters fask Group 7. was not formally established for Operation HARDPACK until October 1957, plans and preparation for its participation in the op*ration started long before that within Headquarters, Joint Task Force SEVFN, and within the headquarters and squadrons of the 950th Test Group (Nuclear) of the Air Force Special Weapons Center. Thus, this report covers activities starting as early as the Spring and Summerof ; 1957. The last shot of the HARDTACK series took place at the Eniwctok Proving Grounds on 18 August 1958, Roll-up activities, deactivation of provisional units, and reassignment of personnel will take place for several ( weeks to come.
