  As is well known, the search for and eventual identification of dark matter
in supersymmetry requires a simultaneous, multi-pronged approach with important
roles played by the LHC as well as both direct and indirect dark matter
detection experiments. We examine the capabilities of these approaches in the
19-parameter p(henomenological)MSSM which provides a general framework for
complementarity studies of neutralino dark matter. We summarize the sensitivity
of dark matter searches at the 7, 8 (and eventually 14) TeV LHC, combined with
those by \Fermi, CTA, IceCube/DeepCore, COUPP, LZ and XENON. The strengths and
weaknesses of each of these techniques are examined and contrasted and their
interdependent roles in covering the model parameter space are discussed in
detail. We find that these approaches explore orthogonal territory and that
advances in each are necessary to cover the Supersymmetric WIMP parameter
space. We also find that different experiments have widely varying
sensitivities to the various dark matter annihilation mechanisms, some of which
would be completely excluded by null results from these experiments.
