81 Division is the youngest Division in the Nigerian Army. The Division was formed on 26 May 2002 when Lagos Garrison Command (as it then was) was upgraded to a full-fledged Division. The Division therefore inherited the security roles hitherto performed by the defunct Lagos Garrison Command. In line with the constitutional roles for the Nigerian Army, 81 Division has operational responsibility to defend part of the South West frontier against any external threat or aggression. The said constitutional provision enables the Division to provide aid to civil authority when ordered to do so.
