  We review recent results on solitons in supersymmetric (SUSY) non-Abelian
gauge theories, focusing on our papers: hep-th/0405194, hep-th/0405129, and
hep-th/0404198. We construct the BPS multi-wall solutions in supersymmetric
U(N_C) gauge theories in five dimensions with N_F(>N_C) hypermultiplets in the
fundamental representation. Exact solutions are obtained with full generic
moduli for infinite gauge coupling. Total moduli space of the BPS non-Abelian
walls is found to be the complex Grassmann manifold SU(N_F) / [SU(N_C)\times
SU(N_F-N_C) \times U(1)]. A 1/4 BPS equation is also studied which gives
combinations of vortices, walls and monopoles. The full moduli space of the 1/4
BPS equation is found to be the space of all holomorphic maps from a complex
plane to the wall moduli space. Exact solutions of the 1/4 BPS equation are
also obtained for infinite gauge coupling.
