“A new commander has been appointed for Operation Lafiya Dole,” army spokesman Brigadier General Sani Usman said in a statement, identifying him as former military logistics chief Major General Rogers Ibe Nicholas.
He takes over from Major General Ibrahim Attahiru, who was appointed to the post just seven months ago and now has been reassigned to the army’s policy and planning department.
No reason was given for the change.
In recent weeks, there has been an upsurge in Boko Haram attacks that have cast further doubt on government and military claims that the jihadists are a spent force.
Last weekend, two suicide bombers killed at least 13 and injured more than 50 in Biu, a town some 185 kilometres (115 miles) south of Borno state capital Maiduguri.
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.
There have also been hit-and-run raids targeting towns, villages and military outposts in the northeast.
One such attack last month saw Boko Haram fighters briefly overrunning Magumeri, a town 50 kilometres north of Maiduguri, forcing troops to withdraw until reinforcements arrived.
The Boko Haram insurgency, which began in 2009, has left at least 20,000 dead and made more than two million others homeless.
