  We study the 3-form gauge theory in the context of generalized BRST
formulation. We construct the finite field-dependent BRST (FFBRST) symmetry for
such a theory. The generating functional for 3-form gauge theory in
noncovariant gauge is obtained from that of in covariant gauge. We further
extend the results by considering 3-form gauge theory in the context of
Batalin-Vilkovisky (BV) formulation.
