  We analyze the Casalbuoni-Brink-Schwarz superparticle model on a
2-dimensional curved spacetime as a super Finsler metric defined on a
(2,2)-dimensional supermanifold. We propose a nonlinear Finsler connection
which preserves this Finsler metric and calculates it explicitly. The equations
of motion of the superparticle are reconstructed in the form of auto-parallel
equations expressed by the super nonlinear connection.
