The pattern is no longer accidental or isolated. It is deliberate, evolving, and deeply troubling.

Across the battlefields of Nigeria’s North-East, a war within a war has quietly taken shape, one in which insurgents are no longer content with attacking formations or inflicting casualties on troops alone. Increasingly, they are aiming higher.

Their targets are the commanders, the men who plan, direct, and sustain the fight.

From the dusty operational corridors of Borno State to the volatile fringes of Yobe and Adamawa, a growing number of Nigeria’s senior military officers, brigadier generals, colonels, and lieutenant colonels, have been killed in action over the last five years.

These are not distant, rear-echelon losses. They are battlefield deaths, occurring at the front where decisions are made under fire.

The recent killing of Brigadier General Braimah alongside a colonel in Benisheikh, Kaga Local Government Area of Borno State, has again brought this disturbing trend into sharp focus.

ISWAP

The attack, widely linked to fighters of the Islamic State West Africa Province (ISWAP), was not just another insurgent strike. It was a calculated blow against leadership itself.

What is becoming increasingly clear is that insurgent groups are adapting.

Rather than merely confronting troops, they are identifying and targeting command structures.

The last five years, at least eight senior officers, four brigadier generals and four colonels have been killed in frontline operations against Boko Haram.

By eliminating senior officers, they create confusion, disrupt coordination, and send a powerful psychological message to troops on the ground.

The Implications are far-reaching. Each fallen commander represents years of battlefield experience lost in an instant. Units are forced to reorganize under pressure. Operational momentum slows.

In a conflict already defined by difficult terrain, stretched logistics, and complex intelligence challenges, the removal of senior leadership adds another layer of vulnerability.

Yet, despite the steady accumulation of these losses, the full scale and significance of the trend have not always been fully examined. This report traces the deaths of key senior officers over the past five years, the circumstances in which they were killed, and what their loss reveals about the changing dynamics of Nigeria’s insurgency war.

Braimah

Benisheikh, a strategic town along the Maiduguri–Damaturu highway in central Borno State, has long served as a key military and logistics hub. Its location makes it critical for troop movement and supply operations across the North-East theatre.

In April 2026, that strategic importance also made it a target.

According to military accounts, insurgents launched a coordinated night assault on a military formation in the area. The attack began with sustained gunfire and quickly escalated into a full-scale engagement, with the use of heavy weapons including rocket-propelled grenades. The intensity of the attack was said to have overwhelmed sections of the defensive line, forcing troops into a prolonged firefight.

At the centre of the battle was Brigadier General Braimah, a frontline commander under Operation Hadin Kai. Known for his direct leadership style, he was reportedly coordinating the defence and directing troops when insurgents breached parts of the formation.

By the end of the battle, he had been killed. A colonel, described by sources as a key operational officer within the unit, also died in the attack alongside several soldiers.

The Nigerian Army, In its response, described the loss as a painful one and praised the courage of the fallen officers. Military authorities reiterated their resolve to continue the fight against insurgency.

However, behind those official statements, the incident raised urgent questions about how such a strategic formation could be penetrated and how insurgents were able to strike with such precision.

Security analysts believe the attack bore the hallmarks of ISWAP, an organised, intelligence-driven operation designed not just to inflict casualties, but to cripple command presence on the battlefield.

Zirkusu

The killing of Brigadier General Dzarma Zirkusu in November 2021 marked one of the clearest early signs that senior officers were becoming deliberate targets.

Zirkusu was on an operational visit to Askira Uba Local Government Area in southern Borno State, a region that had seen intermittent insurgent activity.

His movement was routine, part of ongoing efforts to coordinate operations and assess troop deployment in the area.

However, along the route, his convoy ran into a carefully planned ambush.

Insurgents, believed to be Boko Haram fighters, had positioned themselves along the road, waiting for the convoy to approach. As the vehicles entered the kill zone, the attackers opened fire with heavy weapons, catching the soldiers off guard and leaving little room for manoeuvre.

Zirkusu and three soldiers were killed in the attack.

The Nigerian Army confirmed the incident and paid tribute to the fallen general, describing him as a gallant officer who died in the line of duty. His death drew widespread reaction within military and political circles, with many expressing concern over the exposure of such a senior officer in a high-risk environment.

Beyond the immediate loss, the ambush highlighted deeper operational concerns. It raised questions about route security, intelligence gathering, and the level of situational awareness available to commanders moving through contested territory.

Bako

Earlier in 2021, another senior officer was killed under similarly troubling circumstances.

Colonel Dahiru Bako, Commanding Officer of 25 Task Force Brigade, was leading a reinforcement convoy along the Damboa–Maiduguri road, a critical but highly dangerous route in Borno State.

The road has long been a hotspot for insurgent activity, particularly ambushes and roadside bomb attacks.

As the convoy moved through the highway, an improvised explosive device detonated beneath one of the vehicles, halting movement and throwing the unit into confusion. Almost immediately, insurgents opened fire from concealed positions.

The attack was swift and coordinated.

Colonel Bako was killed alongside several soldiers, while others sustained injuries. The Nigerian Army later confirmed the incident and described him as a dedicated officer who paid the ultimate price in service to the nation.

Security experts attributed the attack to ISWAP, noting the group’s increasing reliance on combined tactics, using IEDs to immobilise convoys before launching direct assaults. The killing reinforced concerns about the vulnerability of troop movements and the risks faced by commanders who travel with frontline units.

Adesope

In 2022, insurgents demonstrated an even more alarming capability, the ability to directly assault and penetrate military formations.

Brigadier General Olayinka Adesope was killed during an attack on a military base in the Bama axis of Borno State. The assault took place at night, when insurgents advanced on the formation in multiple vehicles mounted with heavy weapons.

The attack was sustained and intense. Rocket-propelled grenades and heavy machine gun fire were directed at defensive positions, creating breaches that allowed the attackers to push closer to the core of the base.

Troops mounted resistance, and a prolonged firefight ensued. However, parts of the formation were eventually overrun.

Adesope, who was coordinating the defence effort, was killed during the engagement.

Military authorities acknowledged the incident and praised the bravery of the troops who fought to repel the attackers. Nevertheless, the attack exposed significant vulnerabilities in base defence and underscored the growing sophistication of insurgents.

Analysts widely attributed the assault to ISWAP, which has developed a reputation for coordinated attacks on military positions, often aimed at capturing equipment and asserting dominance in contested areas.

Sakaba, Musa, others

While the deaths of generals tend to draw public attention, a parallel and equally significant trend has been unfolding among mid-level senior officers.

Colonels and lieutenant colonels, those who command battalions and lead tactical operations, have increasingly found themselves in direct combat situations, often with fatal consequences.

In 2023, Colonel Ibrahim Sakaba was killed during an operation in the northern Borno axis, an area that includes the Monguno and Marte corridors. His unit was engaged in active combat with insurgents when the encounter turned deadly.

Although details remain limited, military sources confirmed that Sakaba died while leading his men in battle against ISWAP fighters. His death reflects the level of exposure faced by officers responsible for directing ground operations in volatile area.

In 2024, Colonel Aliyu Musa was killed along the Dikwa–Ngala route, another high-risk corridor in Borno State. His convoy was struck by an improvised explosive device, which destroyed the lead vehicle and caused multiple casualties.

The Nigerian military confirmed the incident and honoured Musa’s service, noting his role in ongoing operations against insurgents.

These incidents illustrate how the nature of the conflict is placing colonels, key operational commanders, directly in harm’s way. They are not only planning operations but actively leading them in environments where insurgents have demonstrated both tactical patience and lethal capability.

Uba

By 2025, the pattern had become unmistakable. Brigadier General Uba was killed during an ambush near the Sambisa forest region in southern Borno State, an area long associated with Boko Haram activity.

Uba was leading troops on a clearance operation aimed at flushing out insurgents from their hideouts when the unit came under sudden attack. Fighters, concealed within the terrain, opened fire in a classic ambush formation.

The assault was rapid and intense, leaving little opportunity for repositioning.

Uba was killed in the exchange.

The Nigerian Army described his death as a major loss and reaffirmed its commitment to ongoing operations in the region. However, the incident once again highlighted the challenges posed by terrain and the advantage insurgents hold in areas they know intimately.

The attack was widely attributed to Boko Haram, whose fighters continue to operate within and around the Sambisa forest using guerrilla tactics.

Pattern

Taken together, observers believe these incidents reveal more than coincidence. They are considered to point to a deliberate shift in insurgent strategy and a persistent vulnerability within the operational environment.

Senior officers are increasingly visible on the battlefield, a reflection of Nigeria’s command culture, which emphasizes leadership from the front. While this approach strengthens morale and ensures direct oversight of operations, it also places commanders within reach of insurgent firepower.

At the same time, insurgent groups appear to have improved their ability to gather intelligence. The timing and precision of several attacks suggest prior knowledge of troop movements or the presence of high-value targets. Whether through informants, surveillance, or other means, this level of awareness has made ambushes and targeted assaults more effective.

The methods themselves have also evolved. Insurgents now combine improvised explosive devices with coordinated gun attacks, or launch large-scale assaults on bases. These are not isolated but structured operations designed to achieve specific outcomes.

War

The continued loss of senior officers carries significant consequences for Nigeria’s military campaign.

Operationally, each death creates a gap in leadership that must be filled under pressure. Successors must quickly adapt, often in the midst of ongoing engagements. This can disrupt planning and slow response times.

Psychologically, the impact is equally profound. Soldiers who see their commanders fall in battle may experience a decline in morale, even as they continue to fight. The symbolic weight of such losses cannot be ignored.

Strategically, the pattern raises critical questions about force protection, intelligence coordination, and the overall conduct of operations. It suggests that while progress may have been made in some areas, insurgents retain the capacity to strike at the core of military leadership.

Loss

What emerges from this five-year trail of loss is a stark and unsettling picture of a conflict that continues to evolve in dangerous ways.

From Askira Uba to Benisheikh, from the Damboa highway to the forests of Sambisa, Nigeria’s senior officers have repeatedly found themselves at the centre of deadly engagements. They have not fallen in distant command posts, removed from danger. They have fallen in the same way as the soldiers they lead.

This reality speaks both to courage andvulnerability. It reflects a military tradition that values visible leadership and shared risk, but it also exposes the cost of that approach in a war where the enemy relies on surprise, mobility, and intimate knowledge of the terrain.

The deaths of Braimah, Zirkusu, Adesope, Uba, Bako, Sakaba, Musa, and others, are not isolated tragedies. They form a pattern that reveals how insurgents are reshaping the battlefield, placing a premium on targeting leadership as a means of weakening the broader war effort.

Security experts argued that until the pattern is effectively addressed through improved intelligence, stronger force protection, and adaptive tactics, the risk will remain that more commanders will be lost in similar circumstances. (Sunday Vanguard)
