Abstract
We review progress in studying the solutions of SQCD in the presence o f explicit, soft SUSY breaking terms. Massive N=1 SQCD in the presence of a small gaugino mass leads to a controlled solution which has inte resting phase structure with changing a angle reminiscent of the QCD c hiral Lagrangian. Current attempts to test the solutions of pure glue SQCD on the lattice require a theoretical understanding of the theory with small gaugino mass in order to understand the approach to the SUS Y point. We provide such a description making predictions for the gaug ino condensate and lightest bound state masses. Finally we briefly rev iew recent D-brane constructions of 4D gauge theories in string theory including a non-supersymmetric configuration. We identify this config uration with softly broken N=2 SQCD.
