Origins of Urban Survival Combat
Urban Survival Combat (USC) is a unique martial system founded by John O’Connor, a Belfast-born veteran of the French Foreign Legion. Though registered under the banner of Karate to align with national and international associations, USC is a synthesis of Tomari-te, Silat, and practical unarmed combat developed during the harsh realities of war and inner-city violence.
What is Silat?
Silat refers to a family of martial arts from Southeast Asia, especially Indonesia, Malaysia, and Brunei. Known for its fluid movement, deadly close-quarter techniques, and integration of spiritual and environmental awareness, Silat evolved as both a warrior art and a cultural tradition. Styles like Silat Harimau use low stances, deceptive footwork, and rapid takedowns — ideal for jungle warfare and survival.
During the First Indochina War, some Silat practitioners were recruited to train elite soldiers and guerrilla forces in ambush, disarmament, and improvised weapon use. John O’Connor is said to have trained with one such master — the legendary but elusive Mahmud Ariffin (b. 1918) — while stationed in Southeast Asia.
What is Tomari-te?
Tomari-te is one of the three foundational Okinawan Karate styles, alongside Shuri-te and Naha-te. Emerging from the village of Tomari, it emphasized speed, agility, and natural stances. Known for kata like Wanshu and Rohai, Tomari-te developed from both indigenous Okinawan techniques and imported Chinese martial arts such as White Crane Kung Fu.
The Creation of Urban Survival Combat
After witnessing the brutality of hand-to-hand combat in the jungles of Vietnam and Laos, John O’Connor began fusing his background in Tomari-te with the deadly efficiency of Silat and the ruthless pragmatism learned in Legion training. He called the result Urban Survival Combat — an adaptable, no-nonsense method suited for back alleys, riot zones, and war zones alike.
- Vital point targeting and disabling strikes
- Low-line kicks, sweeps, and joint attacks
- Improvised weaponry and disarms
- Ground fighting from a survivalist perspective
- Psychological tactics and situational awareness
Though the term “Karate” appears on the club window, John’s students — including notable names like Dan Connolly and Seamus McDonnell — knew they were being taught something far more raw and unpredictable. To this day, USC survives in the teachings of John’s most loyal students, hidden behind the polite structure of grading systems and tournament rules.

Mahmud Ariffin
Date of Birth: 1918
Place of Birth: Surakarta (Solo), Java, Dutch East Indies (now Indonesia)
Biography:
Mahmud Ariffin was a highly respected Pendekar (master) of traditional Javanese Silat Harimau and Silat Serak, born into a lineage of martial artists and herbalists. Trained from childhood by his grandfather — a village protector during the colonial unrest — Mahmud grew up with a deep sense of duty, discipline, and mysticism.
By the 1940s, as colonial tensions escalated across Southeast Asia, Mahmud’s abilities drew attention far beyond his native Java. He became known for his brutal efficiency, unorthodox movement, and ability to neutralize opponents with minimal force. During the First Indochina War (1946–1954), Mahmud was recruited unofficially as a field instructor in hand-to-hand combat for select French Foreign Legion units operating in Laos and northern Vietnam. His presence was kept quiet; officially, he was a “scout,” but to the Legionnaires he trained, he was a ghost-like figure who could teach them how to survive close-quarters ambushes in the jungle.
Many veterans later credited Ariffin’s unique tactics — low stances, deceptive movement, and environmental awareness — with saving lives in the field. Among those he is rumored to have trained was John O’Connor, the Belfast-born Legionnaire who later became a key figure in Irish martial arts.
Mahmud returned to Java after the conflict but continued teaching in secret, refusing to modernize or commercialize Silat. He passed away in 1987, but his teachings survive in scattered notes, legends, and a handful of loyal students who now teach quietly across Southeast Asia and Europe.
Sensei Srisai – 9th Dan, Free-Style Karate
Born in 1920 in Bangkok, Thailand, Sensei Srisai began his journey as a dedicated Muay Thai fighter, known for his toughness and relentless spirit in the ring. To sharpen his skills and broaden his martial understanding, he sought training beyond the Thai tradition and discovered the ancient art of Tomari-te — a style of Okinawan Karate known for its swift, precise strikes and close-quarters techniques.
His Tomari-te training was guided by Sensei Takemura Seiji (竹村 清司), an Okinawan master whose life was profoundly shaped by the turbulent times of the early 20th century. Sensei Takemura was conscripted into the Japanese Imperial Army during World War II, serving in Thailand as part of Japan’s military presence in Southeast Asia. Despite the hardships of war, he remained dedicated to preserving and teaching Okinawan karate, and after the conflict ended, he chose to stay in Thailand to pass on his knowledge.
Under Sensei Takemura’s mentorship, Srisai mastered Tomari-te, blending its refined techniques with his Muay Thai background to create a unique, versatile fighting style. This fusion not only enhanced his combat abilities but also embodied the resilience and adaptability of martial arts traditions crossing cultures and histories.
Today, Sensei Srisai stands as a 9th Dan in Free-Style Karate, a testament to decades of discipline, experience, and the enduring legacy of his Okinawan roots and Thai heritage.
