We simulate $ SU(2) $ lattice gauge theory using dynamical reduced staggeredfermions. The latter lead to two rather than four Dirac fermions in thecontinuum limit. We review the derivation and properties of reduced staggeredfermions and show that in the case of fields in the fundamental representationof $SU(2)$ the theory does not exhibit a sign problem and can be simulatedusing the RHMC algorithm. We present results on lattices up to $16^4$ for awide range of bare fermion masses. We find a single site condensate appears atstrong coupling that spontaneously breaks the one global $U(1)$ symmetryremaining in the reduced fermion action.
