Right. Sonny had Tessio send his regime to guard the compound initially after Vito was shot because he didn't want to use Clemenza's regime at the time. The novel says Neri was sent to take over Tessio's regime. We lose track after that. The whole idea of a NY family with just a couple or three capos doesn't make sense, but none beyond that are indentified in the novel or movie, so we're stuck with that.

It was probably Rocco's regime that ended up in NV with Michael.
