Academic Excellence and Military Training
Nigerian Defence Academy Education
Brigadier General Oseni Braimah’s military journey began at the Nigerian Defence Academy, Nigeria’s premier institution for training military officers. At the NDA, he pursued a Bachelor of Arts degree in History, which provided him with a strong foundation in understanding strategic military campaigns, geopolitical contexts, and the historical evolution of warfare.
The five-year Regular Combatant Course at NDA combines rigorous military training with academic education, producing officers who are both intellectually equipped and physically prepared for the demands of military leadership. Braimah excelled in this demanding environment, demonstrating the discipline and intellectual capacity that would define his career.
Upon graduation in September 2000, he was commissioned as a Second Lieutenant in the Nigerian Army, marking the official beginning of his military service. This commissioning ceremony, presided over by the President of Nigeria, represented the culmination of years of intensive training and the start of his lifelong commitment to defending Nigeria.
Advanced Military Education
Understanding that modern warfare requires continuous learning, General Braimah pursued multiple advanced degrees throughout his career. Between 2004 and 2006, he earned a Master of Arts in International Relations and Strategic Studies from Benue State University, broadening his understanding of global security dynamics and diplomatic relations.
His pursuit of excellence took him to Pakistan, where he obtained a Master’s degree in National Security Management and War Studies from the prestigious National Defence University in Islamabad. This international education exposed him to diverse military doctrines and strategic frameworks used by armies worldwide.
Perhaps his most significant academic achievement was earning a Master of Arts in Defence Studies from King’s College, London, between 2016 and 2017. King’s College is renowned globally for its Department of War Studies, and this qualification placed Braimah among the most academically qualified military officers in Nigeria.
He also obtained a Diploma in Strategic Leadership and Management from the Chartered Management Institute (CMI), demonstrating his commitment to developing leadership skills beyond purely military competencies. This diverse educational background equipped him with the theoretical knowledge to complement his practical field experience.
Distinguished Military Career
Early Career and Field Experience
After his commissioning in 2000, Brigadier General Braimah began accumulating valuable field experience across various formations within the Nigerian Army. His early years involved commanding troops at platoon and company levels, where he developed the foundational leadership skills that would serve him throughout his career.
His competence and dedication earned him selection for increasingly responsible positions. Between 2011 and 2012, he served as an Observer with the United Nations, gaining international peacekeeping experience that exposed him to multinational military operations and diverse conflict environments.
In 2014, he was appointed Deputy Chief of Staff at the Headquarters of the Guard Brigade, one of Nigeria’s most prestigious military formations responsible for protecting the seat of government in Abuja. This position placed him at the heart of Nigeria’s military command structure and demonstrated the trust senior commanders had in his abilities.
Operation Hadin Kai Service
From December 2019 to May 2021, General Braimah served as Chief J3 (Deputy Chief of Staff, G3) at the headquarters of Operation Hadin Kai in Northeast Nigeria. This position placed him in charge of operations and training for the entire theater command fighting Boko Haram and ISWAP insurgents.
Operation Hadin Kai represents Nigeria’s primary counter-insurgency effort in the Northeast, involving thousands of troops deployed across Borno, Yobe, and Adamawa states. As Chief J3, Braimah was responsible for planning military operations, coordinating tactical movements, and ensuring troops received appropriate training for counter-insurgency warfare.
This experience gave him intimate knowledge of the insurgency’s tactics, the terrain challenges in Borno State, and the complexities of civilian-military relations in conflict zones. The operational insights he gained during this period would later inform his approach as Brigade Commander.
International Diplomatic Service
From May 2021 to August 2024, Brigadier General Braimah served as Defence Adviser at the Nigerian High Commission in Islamabad, Pakistan. This diplomatic posting represented recognition of both his academic credentials and his ability to represent Nigeria’s military interests abroad.
As Defence Adviser, he served as the primary liaison between the Nigerian and Pakistani militaries, facilitating defense cooperation, military training exchanges, and intelligence sharing. His previous academic training in Pakistan likely influenced his selection for this prestigious posting.
This international exposure broadened his perspective on global security challenges and allowed him to study Pakistan’s own counter-insurgency experiences, which have parallels to Nigeria’s fight against Boko Haram and ISWAP.
Final Postings
Between September 2024 and March 2025, General Braimah served as Chief of Staff at the 6 Division Headquarters of the Nigerian Army in Port Harcourt, Rivers State. This position involved coordinating the activities of all staff sections within the Division and ensuring efficient implementation of operational directives.
His final posting came in March 2025 when he was appointed Commander of the 29 Task Force Brigade Headquarters in Benisheikh, Borno State. This frontline command placed him directly in harm’s way, responsible for securing one of the most volatile areas in Northeast Nigeria and protecting local communities from insurgent attacks.
The Fatal Attack of April 9, 2026
The Night of Terror
At approximately 12:30 a.m. on April 9, 2026, ISWAP insurgents launched a coordinated assault on multiple military formations across Borno State. The primary target was the 29 Task Force Brigade Headquarters in Benisheikh, Kaga Local Government Area, under the command of Brigadier General Braimah.
The terrorists attacked with heavy gunfire and explosives, attempting to breach the defensive perimeter of the military installation. Intelligence reports suggest the assault was carefully planned, with simultaneous diversionary attacks on Pulka and Ngamdu designed to prevent rapid reinforcement.
According to local sources, the insurgents fired sporadically at the military facility, causing numerous casualties and setting combat vehicles ablaze. The attack lasted several hours, during which Brigadier General Braimah personally led the counteroffensive from the front lines.
Heroic Last Stand
Major General Michael Onoja, Director of Defence Media Operations, confirmed that General Braimah led his troops with “exceptional courage, professionalism, and superior firepower” during the encounter. Rather than directing operations from a protected command post, the General engaged the insurgents directly in coordinated counterattacks.
Eyewitness accounts from community leader Zanna Lawan Ajimi confirmed that General Braimah was among those killed during the intense firefight. Also killed were his second-in-command and the Brigade Imam, along with 15 other soldiers who fought valiantly to defend the base.
Unconfirmed sources suggested that General Braimah fell when his armored vehicle failed him during the heat of battle, exposing him to direct insurgent fire. This tragic detail, if accurate, highlights the equipment challenges Nigerian troops face in counter-insurgency operations.
The insurgents were ultimately forced to retreat in disarray, abandoning their mission to overrun the base. However, the price paid for this defensive victory was devastating, with 18 Nigerian soldiers making the ultimate sacrifice.
National Response
President Bola Tinubu personally confirmed General Braimah’s death in a statement released on April 9, 2026: “I extend my condolences to the families of our gallant soldiers, led by Brigadier-General Oseni Omoh Braimah, who made the ultimate sacrifice in the defence of our country today in Borno State. The government will never forget their sacrifices.”
The President framed the attack as a sign of insurgent desperation following sustained military offensives that had neutralized many ISWAP fighters and commanders. He urged the military leadership and frontline troops not to be discouraged, promising continued government support in equipment and welfare.
Legacy and Impact
Brigadier General Oseni Braimah’s death represents a significant loss for the Nigerian Army and the nation. As one of the most educated and experienced officers in counter-insurgency operations, his strategic insights and operational expertise will be sorely missed.
His sacrifice highlights the ongoing dangers faced by Nigerian troops in the Northeast, where over a decade of insurgency has claimed thousands of military and civilian lives. The death of such a senior commander in a direct assault on a brigade headquarters underscores the persistent threat ISWAP poses to military installations.
General Braimah’s leadership style—characterized by leading from the front rather than directing from safety—exemplifies the warrior ethos that inspires troops but also exposes senior commanders to mortal danger. His willingness to share the risks with his soldiers earned him deep respect among subordinates.
His extensive academic background demonstrated that Nigeria’s military officers can combine battlefield prowess with intellectual depth, producing scholar-warriors capable of both tactical execution and strategic thinking. Future officers will study his career as an example of professional military education.
The 18 soldiers who died alongside General Braimah represent Nigeria’s continued commitment to defeating terrorism despite the heavy cost. Their sacrifice reminds Nigerians that military service demands the ultimate price from those who volunteer to defend the nation.
