Who are the marshals in Yellowstone? Kayce's new unit includes the man who led his SEAL team
Kayce Dutton left the ranch and joined a federal task force, which means a whole new set of names to keep straight. The spinoff also quietly dropped the "Y" from its original title, Y: Marshals, in January 2026 — it's just Marshals now. Here's who's on the team.
Kayce's Montana unit has four other members: Pete Calvin, Belle Skinner, Andrea Cruz, and Miles Kittle. Calvin runs it. He's also Kayce's former commanding officer from their Navy SEAL days, which is how Kayce got the job in the first place — Calvin offered it to him after Monica's death.
The unit, member by member
- Pete Calvin (Logan Marshall-Green) — head of the Montana unit, called "Cal" by the team. Kayce's old SEAL team leader, and the one who recruited him.
- Belle Skinner (Arielle Kebbel) — undercover specialist and former ATF agent. Wife and mother, and cagey about her own history.
- Andrea Cruz (Ash Santos) — Bronx-born and combative, willing to confront Kayce about the Dutton family 's record and to work around her boss when it suits her.
- Miles Kittle (Tatanka Means) — the youngest of the group, a Marine Corps veteran and former Broken Rock Reservation officer with deep ties on the rez.
Above all of them sits Harry Gifford (Brett Cullen), head of Montana's U.S. Marshals division and a cabinet member, who is not thrilled about a Dutton joining the payroll.
Who carried over from Yellowstone
Three familiar faces: Gil Birmingham as Thomas Rainwater, Mo Brings Plenty as Mo, and Brecken Merrill as a now-teenage Tate Dutton. The ranch was sold to Broken Rock, which keeps Kayce and Rainwater in the same rooms. Kelsey Asbille does not return — the premiere establishes that Monica died of cancer in the gap between the two shows.
Who made it
Not Taylor Sheridan, at least not as writer. Marshals was created by Spencer Hudnut, previously showrunner of SEAL Team, making it the first Yellowstone spinoff Sheridan didn't write; he's an executive producer. It's also the franchise 's first broadcast network series.
Did it work?
Numbers say yes. The March 1, 2026 premiere pulled 20.6 million multiplatform viewers within a week — CBS's most-watched original series premiere without a football lead-in since Young Sheldon in 2017, and its most-streamed episode ever on Paramount+.
CBS renewed it on March 12, after two episodes had aired.
Season 1 ran 13 episodes and finished May 24, 2026. Season 2 premieres October 4, 2026 at 8:30/7:30c before settling back into the Sunday 8/7c slot.
