According to the Sopranos book by Allen Rucker, Vito Spatafore is a "soldier" in the Aprile Crew, which was formerly headed by Jackie Aprile Sr. and later by his brother Richie Aprile. This is the crew that Ralphie is now the capo of.

Patsy Parisi is listed as a "soldier" in the Tony Soprano crew, underneath the capo (Paulie) and equal to the Pussy, Gigi Cestone, and Furio Giunta.

I guess in this book, a soldier is a made member.
