  We construct a generalization of the McLerran-Venugopalan (MV) model
including helicity effects for a longitudinally polarized target (a proton or a
large nucleus). The extended MV model can serve as the initial condition for
the helicity generalization of the JIMWLK evolution equation constructed in our
previous paper, as well as for calculation of helicity-dependent observables in
the quasi-classical approximation to QCD.
