The Defence Headquarters has given top officers who are seniors to the newly appointed service chiefs till Monday to voluntarily retire from service.
The order, which was contained in a memo dated June 26 and signed by Maj Gen Y. Yahaya on behalf of the Chief of Defence Staff, was directed to generals, brigadiers-general, air vice marshals, and rear admirals in the Nigerian Army, Air Force, and Nigerian Navy, who are senior to the new service chiefs.
A report by the PUNCH confirms that scores of top military brass would be retired following the appointment of new service chiefs by President Bola Tinubu on June 19.
The retirement of the senior officers across the three services was in line with the long-standing military tradition that officers who were senior to the service chiefs would be retired.
It is a tradition in the military that when a junior is appointed as a service chief, senior officers, who are ahead of him or her, would proceed on retirement.
The understanding is that senior military officers are unlikely to take orders from their juniors.
Tinubu had announced the immediate retirement of General Lucky Irabor who was the Chief of Defence Staff; the Chief of Army Staff, Lieut Gen Farouk Yahaya; the Chief of Naval Staff, Vice Admiral Awwal Gambo, and Air Marshal Oludayo Amao, the Chief of Air Staff and replaced them with new military chiefs.
The new service chiefs are Maj Gen Christopher Musa who is the Chief of Defence Staff; the Chief of Army Staff, Maj Gen Taoreed Lagbaja; the Chief of Naval Staff, Rear Admiral Emmanuel Ogalla while Air Vice Marshal Hassan Abubakar was appointed the Chief of Air Staff.
DIG Kayode Egbetokun was appointed as the acting Inspector-General of Police and Maj. Gen. E Undiandeye, Chief of Defence Intelligence.
Also, a former Economic and Financial Crimes Commission Chairman, Nuhu Ribadu, who was earlier appointed as the Security Adviser to the President, was elevated to the National Security Adviser.
While the new CDS is a member of 38 Regular Course, the COAS, the CNS, and the CAS are members of 39 Regular Course.
However, the DHQ in the memo with reference number DHQ/I5/PLANS/801/13 directed all officers with seniority on commission above that of Nigerian Defence Academy Regular Course 39 to submit their applications for voluntary retirement from service with immediate effect.
This, it said, was meant to preserve and uphold the tenets of the military profession which values hierarchy and service discipline.
