FIRE CAST: THOSE IN CHARGE Eamonn Walker as Battalion Chief Wallace Boden

Appearing alongside the Chicago Fire cast since the beginning, Walker plays Battalion Chief Wallace Boden, the man in charge at Firehouse 51. Taking his role seriously, Boden is very protective of his crew and isn’t afraid to put his own neck on the line for them. Understanding his devotion, the Chief gets promoted to Deputy District Chief in season 10. Taylor Kinney as Lieutenant Kelly Severide Also working alongside the veteran Chicago Fire cast since day one, Kinney portrays Lieutenant Kelly Severide, the officer in charge of Squad 3. Severide has a history with the Chicago Fire Department, as his father previously served as Fire Chief.

However, his dedication and service proved that this wasn’t a job handed to the young man, but one earned. Charming, Kelly began the show as a “ladies’ man.” However, he put his flirtatious days to rest after he began dating Stella Kidd in season five. The pair became engaged in season nine and officially tied the knot during the show’s season 10 finale. After it was announced that Taylor Kinney would take a leave of absence from Chicago Fire, the show bid Lieutenant Severide a (temporary?) farewell halfway through Season 11. Severide was written off when he is sent away for arson investigation training, and his character won’t return for the remainder of the 11th season. CHICAGO FIRE CAST: THE FIREFIGHTERS Joe Miñoso as Firefighter Joe Cruz Miñoso has portrayed Joe Cruz as an integral part of the Chicago Fire cast since season one.

With a troubled upbringing, he was raised in some of the city’s worst neighborhoods rife with gang violence. He even spends a major portion of the early seasons helping his younger brother out of trouble. Cruz was the truck driver for Truck 81 up until season three. Since then, he has driven for Squad 3. In the eighth season, he marries Chole Allen. The two welcome their firstborn son in season 10. Christian Stolte as Firefighter Randy “Mouch” McHolland Another senior firefighter in the Chicago Fire cast, Stolte plays fan-favorite Randy McHolland. To the crew, however, McHolland simply goes by “Mouch” a combination of “man” and “couch” to signify where and what the firefighter is best known for when off-duty at the station.

But Mouch does much more than he appears. He serves as the stations union rep, and oftentimes as a legal advisor. He also is the co-owner of Molly’s bar with Herrmann. In the fourth season, he married Sergeant Trudy Platt as part of a crossover with the character from Chicago P.D. Miranda Rae Mayo as Firefighter Stella Kidd Mayo may not be part of the O.G. Chicago Fire cast, but fans quickly fell in love with her portrayal of Stella Kidd after she was introduced in season four. Kidd started her journey as a firetruck driver. But after passing her exams in season nine, she is promoted to become Lieutenant. When Kidd joins Firehouse 51, she finds herself recently divorced. Soon after, she rekindles a past love interest with Lieutenant Kelly Severide.

Proving that theirs must have been a long-lost love, the two tie the know at the end of season 10. Daniel Kyri as Firefighter Darren Ritter Kyri plays one of the newcomers in the Chicago Fire cast, joining the crew in season seven. Ritter was transferred to the Firehouse at the recommendation of Mouch, who helped him break through some issues during a fire in which he made his first live saving maneuver. Though troubled at times, Ritter is determined to follow in the footsteps of his Uncle, who served as a FDNY firefighter.
