We review results on leading particles from hadron-nuclear collisions. We conclude that the partons (quarks or diquarks) which produce the leading particles are not strongly absorbed as they emerge from the struck nucleus. In contrast an examination of the partons that give rise to the low energy pions and nucleons seems to indicate some kind of cascade occurs in the struck nucleus. There is on the average only one massive string produced in these collisions. The multiplicity produced by the hadronization of the massive strings is quite consistent with that produced in {ital e}{sup +}{ital e}{sup {minus}} annihilations. {copyright} {ital 1996 The American Physical Society.}
