…Shake-up triggers generational shift, as over 160 Generals to retire
…Retired Generals applaud ‘return to military tradition’
President Bola Ahmed Tinubu’s major shake-up of the nation’s security architecture has continued to generate widespread reactions from both within and outside the military establishment.
Recall that on Friday, the President announced the removal of General Christopher Musa as Chief of Defence Staff (CDS), replacing him with Lieutenant-General Olufemi Oluyede. Other new appointments include: Major-General W. Shaibu as Chief of Army Staff, Air Vice-Marshal S.K. Aneke as Chief of Air Staff, and Rear Admiral I. Abbas as Chief of Naval Staff, while Major-General E.A.P. Undiendeye retains his position as Chief of Defence Intelligence.
The President’s sweeping overhaul has set-off one of the largest waves of retirements in the Armed Forces in recent years, with over 160 senior officers expected to bow out following the appointment of new Service Chiefs.
The shake-up comes just days after reports of an alleged coup attempt – dismissed by the Presidency as fake news – sparked nationwide debate over military loyalty and leadership stability.
Speaking through his Special Adviser on Media and Public Communication, Sunday Dare, President Tinubu said the decision was a routine exercise within his constitutional authority as Commander-in-Chief.
“This is routine, meant to boost security across the nation”, Dare said. “The Commander-in-Chief can at any time make these changes to strengthen command structures and ensure efficiency”.
However, beyond the official explanation lies a far-reaching generational turnover dictated by military tradition and hierarchy. Under the Harmonised Terms and Conditions of Service (Revised 2024), officers senior to the new Service Chiefs – who belong to the 41 Regular Course – must automatically retire.
With General Oluyede (41 RC) now serving as Chief of Defence Staff, and the new Army, Navy, and Air Force chiefs drawn from the 40 and 41 Regular Courses, all officers from the 39 and 40 Courses are expected to proceed on compulsory retirement.
By current estimates, the Army alone will lose over 120 senior officers, while about 40 more will exit from the Navy and Air Force combined – amounting to roughly 160 top military personnel leaving the service.
The new Chief of Army Staff, Major-General W. Shaibu, belongs to the 41 Regular Course commissioned in 1994 – the first batch of officers trained under the regime of the late General Sani Abacha. His appointment effectively ushers in a new generation of military leadership trained in the mid-1990s, replacing officers who began their careers in the 1980s and early 1990s.
Retired military leaders have largely welcomed the move, describing it as a timely correction of structural imbalances that have long hindered career progression within the Armed Forces.
Retired General Anthony Atolagbe told reporters: “There will be excitement in the military because of this change. It restores the old rhythm – two years for Service Chiefs, then rotation. That ensures younger officers can move up without stagnation”.
Another retired General noted that previous administrations had allowed Service Chiefs to overstay their tenure, which “dislocated the chain of succession” and led to “early retirement of many highly trained officers”.
For the rank-and-file, the latest changes bring both relief and apprehension. While younger officers see new opportunities for advancement, those affected face an abrupt end to decades-long careers.
Military insiders describe the overhaul as a “generational reset” — one that clears out the old guard, opens long-blocked promotion lines, and repositions the services for renewed vigor in tackling Nigeria’s persistent security challenges. As one serving officer who spoke anonymously put it: “If the political class genuinely supports the military and gives it clear direction, this change could mark a new era of effectiveness. The tools are there — what has been missing is decisive leadership”.
With this realignment, the 41 Regular Course now dominates the upper echelons of the Armed Forces, signaling a new chapter in Nigeria’s military history – one defined by generational transition, strategic recalibration, and the unmistakable stamp of President Tinubu’s command.
Friday’s appointments mark the second major overhaul of the Armed Forces since Tinubu assumed office in 2023, when he appointed a new set of Service Chiefs and Nuhu Ribaɗu as National Security Adviser, (NSA).
Recall that following the death of then Chief of Army Staff, Major-General T.A. Lagbaja in October 2024, Tinubu had earlier appointed General Olufemi Oluyede as his replacement — who now assumes the role of Chief of Defence Staff in this latest shake-up.
