Efforts to form an umbrella body to represent the interests of Ex-Boys of Nigerian Military School, Zaria dates back to the mid-60s. Notable amongst such early gatherings was the one that usually held at a hotel around Ojuelegba, Lagos. Such gatherings continued in various locations where ExBoys were found in large numbers but because of the unfavorable disposition of the governments at the time, formal approval could not be obtained.

It is this early congregation of Ex-Boys in such locations that made it possible for a very large number of Ex-Boys to attend the School's 21st Foundation Day ceremony in 1975 which had a distinguished Ex-Boy, Brig. Gen. EE Ikwue (Rtd) of the 1st Platoon as the reviewing officer of the parade.

After this, Ex-Boys have made concerted efforts to be involved one way or the other in the affairs of our dear Alma mater. Unfortunately, due to the several coups associated with that era and the security implications of allowing military men meet in un-monitored settings and also against the backdrop that the military is the single largest constituency of Ex-Boys, many Ex-Boys' activities went underground though some Ex-Boys convened by Ex-Boy Nurudeen Dalemo were still said to be meeting at Mopet Restaurant owned by Ex-Boy (Engr.) Peter Owolabi.

While all these small group meetings were going on, efforts were made by Ex-Boys in service to convince the Army Headquarters to officially allow ExBoys to meet and this culminated in the authorization by the then Chief of Army Staff in June, 1994 to the Director of the Nigerian Army Education Corps to instruct the Commandant of the Nigerian Military School to launch the Ex-Boys Association.

The pioneer steering committee of the ExBoys' Association as appointed by the Army headquarters had Ex-Boys (Maj Gen) IBM Haruna, ExBoy Nurudeen Dalemo and Ex-Boy (Flt Lt) MU Salisu as members. The authorization was announced at the Passing Out Parade of July, 1994. A Board of Trustees with a broad representation was appointed and a dra constitution was produced. The Association was registered in March 1995 and meetings continued at the states and national levels. By May 1995, the Association had taken over the celebration of the school's Foundation Day celebration after which state chapters as well as campus chapters took off.

The Association thrived until 1997 when there was a down turn in the business of the then Secretary General (Ex-Boy MU Salisu). The dues being collected then were not enough to carry out activities and the Association could not even pay for the meeting venues. Apart from the financial downturn of the Secretary-General's business, the political climate of the nation at the time was also marked with uncertainty. Consequently, the only a semblance of life the Association had were few and far between scanty meetings.

In the course of time, some younger elements who had hitherto started relating on the social media - which eventually culminated into physical meetings - saw the need to set up a formal structure and decided to register an Ex-Boys' Foundation and were galvanizing support for a formal launch. At the same time, some more senior Ex-Boys were marking the 80th Birthday of a former Commandant, Gen. Ogundeko in 2012.

This occasion brought to their knowledge, the newly registered Ex-boys' Foundation. The Foundation's launch was well attended by ExBoys of several generations on 1st December, 2012. Aer the launch, several meetings were convened with a view to harmonize both bodies and at a meeting held in April 2013, at Amana Suites, Wuse Zone 5, Abuja, it was agreed that the Foundation should be relegated while members of both bodies will form the Interim National Executive headed by Exboy (Cdre) FD Onimole.

The Ex-Boy Onimole-led Interim Executive inaugurated the Lagos, Abuja, Kaduna and Port-Harcourt chapters. It also led the Association to the Golden Jubilee Celebration of NMS in May, 2014 whereat it conducted elections and handed over to the Ex-Boy (Col) JM Hassan-led Executive which in turn inaugurated Plateau, Kwara and Kano chapters, among others.

Upon completing her tenure in May, 2016, elections were conducted and the Ex-Boy (R/Adm) GSA Ombo-led Executive came on board. They have since been been working assiduously towards consolidating on the successes recorded by the previous Executives.
