Generalizations of the St\"uckelberg decomposition of a vector field are developed by means of the Feynman functional-integral technique. The modified perturbation series which result are of interest because they can be used to express the nonrenormalizable parts of the interaction of a system of charged massive vector particles in a form to which recently developed nonpolynomial techniques of computation can be applied.
