Lieutenant general (Lt Gen), is the second-highest rank of the Nigerian Army and generally it is the highest active rank as the Nigerian army do not have any appointment in the rank of full general but in the case of the appointment of Chief of Defence Staff, the rank of full general is given (if the chief is appointed from the army and not from the navy or the air force). It is the equivalent of a multinational three-star rank.
The rank of lieutenant general is usually held by the Chief of Army Staff.
Lieutenant general is a superior rank to major general, but subordinate to a (full) general. The rank has a NATO rank code of OF-8, equivalent to a vice-admiral in the Nigerian Navy and an air marshal in the Nigerian Air Force (NAF) and the air forces of many Commonwealth countries.
The rank insignia is an eagle and a six-pointed star over a crossed sabre and baton.
