Jason Fox, known for his role in the Channel 4 series SAS: Who Dares Wins and his extensive military background, is opening up about his relationship with his brother, Mathieu. The pair, who grew up on the outskirts of Luton, share a deep connection forged through a childhood filled with both playful camaraderie and sibling rivalry. Their story, recently shared, highlights a bond that has endured despite a challenging upbringing and the stresses of post-military life.
Fox, a former Royal Marine Commando and UK Special Forces sergeant, joined the military at just 16 years ancient and served for two decades before being medically discharged in 2012 following a diagnosis of post-traumatic stress disorder. He has since become a prominent television personality and advocate for veterans’ mental health, co-founding the charity Rock2Recovery and touring with his show Embrace the Chaos, which begins on March 10th. Despite his demanding career, the connection with his brother remains a constant.
A photograph accompanying the discussion shows the brothers in 1984 and again in 2026, illustrating the passage of time and the enduring nature of their relationship. The image captures a shared history, a history marked by a childhood spent largely outdoors. According to Fox, their family didn’t have much money growing up, and clothes were often hand-me-downs, with Mathieu inheriting Jason’s garments a couple of years later.
The brothers’ childhood wasn’t without its scrapes. They grew up climbing a tree in their grandparents’ garden, and Mathieu, according to Jason, consistently pushed the boundaries. “He would always go too far up,” Fox recalled, recounting an incident where Mathieu fell from the tree. This playful risk-taking was a defining characteristic of their early years, a contrast to Jason’s more cautious approach. While Jason described having an “inbuilt appreciation of risk,” Mathieu was the one more prone to “doing naughty stuff.”
Mathieu Fox now works as a tree surgeon, a profession that perhaps nods to their shared childhood adventures. Jason Fox’s career path, however, led him to the elite ranks of the British military. He served with the Royal Marines from 1992, and later joined the Special Boat Service, reaching the rank of Sergeant. His experiences in the military, and the subsequent struggle with PTSD, are documented in his books, Battle Scars and Life Under Fire, and explored in documentaries like The Final Mission: Foxy’s War.
Despite the different paths they’ve taken, the core of their relationship remains. “We still connect like we did, only without the fighting or falling out of trees,” Jason Fox said, reflecting on their enduring bond. This sentiment underscores a relationship that has evolved and matured, retaining its fundamental strength despite the challenges of life and the demands of their respective careers.
Jason Fox’s operate continues to focus on supporting veterans and raising awareness about mental health. He is currently touring the UK with his show, Embrace the Chaos, and remains a prominent figure on television. His story, and the story of his relationship with Mathieu, offers a glimpse into the complexities of brotherhood, resilience, and the enduring power of family connections.
What does the future hold for Jason Fox as he continues to navigate his career and advocate for veterans’ mental health? His ongoing work promises to bring further attention to these important issues and inspire others to embrace their own challenges.
