The service chiefs were appointed immediately General Buhari came to power in 2015 as follows ; Defense Chief Abayomi Olonisakin, Army Chief Tukur Buratai,  Navy Chief Ibok-Ete Ekwe Ibas and Air Chief Sadique Abubakar.
They were recently removed and all have been nominated for ambassadorial positions by General Buhari. to be approved by the Nigeria National Assembly.

Under their watch, genocides, massacres, slaughtering of the Nigerians were carried out by combined criminal terrorists such as Bokoharam, ISWAP, Bandits, insurgents etc. Even the Nigeria armed personnel were not spared as many of them were deliberately setup for the terrorists to be ambushed and killed.

The rapid nominations as ambassadors by General Buhari is an attempt to grant them diplomatic immunities from possible prosecutions in the International criminal court of justice (ICC) for crimes against humanity.
