We calculate production cross sections for gluinos and squarks produced in association with charginos and neutralinos at {ital pp} supercollider energies. We show that, with rather stiff cuts, a signal for {ital {tilde g}{tilde Z}}{sub 1} and {ital {tilde q}{tilde Z}}{sub 1} may be isolated from the standard-model background as well as from other supersymmetric processes; this channel may offer the best hope of a gluino mass measurement. We also estimate potential signal rates from hemispherically separated multilepton-plus-jet events that result if the chargino or neutralino decays via the purely leptonic mode.
