Attahiru served as the Theatre Commander, Operation Lafiya Dole, before he was removed from the position barely nine months after he was appointed in 2017.

Some of the operations he led resulted in the killing of two key Boko Haram commanders, Abdu Kawuri and Abubakar Benishek, at Alafa in the Bama Local Government Area of Borno State.
His redeployment followed the deadliest attacks by Boko Haram insurgents on Biu town in Borno where at least 18 people were killed and 52 others seriously injured.
General Attahiru was redeployed to Nigerian Army Headquarters as Deputy Chief of Policy and Plans. 
He was former General Officer Commanding, 82 Division of the Nigerian Army, Enugu.
