A superfield action is proposed within an OSp(4/2) framework whose component form reproduces the covariant xi -gauge Yang-Mills action, but with modified ghost-compensating terms. (The case xi =0 reduces to the usual Landau gauge.) 'Supertranslations' give rise to extended BRS transformations, and lead to constraints amongst the renormalisation constants. In addition, the system admits 'super-Lorentz' transformations, which mix vector and ghost fields. For other field representations, the ghost structure suggested by the space-time supersymmetry OSp(4/G) is also exhibited. This simplifies the results for counting ghosts and their own ghosts.
