  After briefly reviewing the nonperturbative dynamics of N=1 supersymmetric
field theories, soft SUSY breaking mass terms are introduced into the SUSY
gauge theories and their effects on gauge symmetry breaking pattern are
studied. For $N_f<N_c$, we include the dynamics of the non-perturbative
superpotential and use the original (s)quark and gauge fields. For $N_f>N_c+1$,
we formulate the dynamics in terms of dual (s)quarks and a dual gauge group
SU(N_f-N_c). The mass squared of squarks can be negative triggering the
spontaneous breakdown of flavor and color symmetry. The general condition for
the stability of the vacuum is derived. We determine the breaking pattern,
derive the spectrum, and argue that the masses vary smoothly as one crosses
from the Higgs phase into the confining phase exhibiting the complmentarity.
