TheCable understands that Ibrahim has been replaced by Major General Rogers Nicholas who was formerly in charge of logistics at the army headquarters.
Army chief Gen Tukur Buratai gave him a deadline in July to deliver Boko Haram leader Abubakar Shekau dead or alive within 40 days.
"Troops of 202 Battalion, Sector 1, Operation LAFIYA DOLE at the early hours of Monday Dec.4, sprang an ambush on unsuspecting Boko Haram terrorists along Sabsawa axis".
The insurgents continued to stage daring attacks including on military formations.
The dead included soldiers and an oil exploration team.
Among the perceived shortcomings of the outgoing commander was the prosecution of the war against Boko Haram in the North-East, which had lately led to attacks on military bases, the most recent being in the Magumeri Local Government Area of Borno State.
On November 21, another suicide bomber blew himself up killing at least 50 worshippers at a mosque in Mubi, a town in Adamawa state, northeast Nigeria. Mr. Ibrahim had a closed door session with the defence chief.
Ibrahim is expected to resume as Deputy Chief of Policy and Plans at the Army Headquarters.
The latter is the former Commander of the special Security Task Force (operation Safe Haven) in Jos.
Although the army has not officially announced the new deployments to Nigerians, the military radio in Borno has already made the announcements.
