CHAPTER 3
SUMMARY OF RESULTS
Details of the original scientific concept
of the Operation, complete descriptions of test
devices, device yield, and performance data are
omitted from this report, since details of this
information have been included in the Final Op-
eration HARDTACK Report of CTG 7.1 to
CJTF-Seven. This information is available from
CTs 7.1 of JTF-Seven on a “need-to-know”
asis.
