We examine low energy sparticle mass-spectrum and electroweak symmetry
breaking (EWSB) in the mixed modulus-anomaly mediation which is naturally
realized in KKLT flux compactification. We find that the anomaly-mediation
effectively lowers messenger scale in the moduli-mediation and leads to
'squeezed' mass-spectrum distinct from any known mediation mechanisms. The
lightest neutralino typically becomes a mixed state of bino and higgsino or
pure higgsino, which has a considerable impact on the cold dark matter physics.
