  Influenced by the current trend of experimental data, especially from the
LHC, we construct a supersymmetric scenario where a natural dynamics makes the
squarks and gluino super-heavy (order 10 TeV) while keeping the sleptons and
the weak gauginos light (100-500 GeV). The dynamics relies on the interfusion
of two underlying ideas: ($i$) gauge mediation of supersymmetry breaking with
two messenger multiplets, one transforming as a triplet of weak SU(2) and the
other as an octet of color SU(3); ($ii$) perturbative gauge coupling
unification at the string scale even with these incomplete SU(5) multiplets.
Interestingly, the relative magnitude of the triplet and octet messenger scales
that ensures gauge unification at the two-loop level also helps to naturally
keep the uncolored superpartners light while making the colored ones heavy.
