The introduction of space-time lattice as a regulator of path integral breaks symmetries associated with continuous space-time i.e. Poincare invariance and supersymmetry. Due to non-zero bare gluino mass in the supersymmetric Yang-Mills theory the chiral symmetry is also broken. Provided that there are no SUSY-anomalies the lattice form of Ward identities can be used, by imposing that their continuum form should be recovered when removing the lattice regulator, to obtain chiral limit where the theory is characterized by massless gluinos.
