We investigate off-resonance chargino-neutralino production via the reaction [ital p[bar p]][r arrow][ital W][sup *][r arrow][ital [tilde W]][sub 1][ital [tilde Z]2][ital X] within the framework of the minimal supersymmetric standard model (MSSM) at the Fermilab Tevatron collider. This reaction can lead to observable rates for hadronically quiet trilepton events for which standard model backgrounds are small. Evaluation of these rates allows us to conclude that, after the accumulation of 100 pb[sup [minus]1] of integrated luminosity, the collider detector at Fermilab and D0 experiments can explore significant regions of MSSM parameter space beyond the reach of the CERN [ital e][sup +][ital e[minus]] collider LEP, and in some cases beyond the reach of LEP 200. The dilepton signal from chargino pair production is also briefly discussed.
