Nigeria's military has begun moving its headquarters to the northern town of Maiduguri, it says, close to the centre of the Boko Haram Islamist insurgency.
The move would "add impetus and renewed vigour" to the fight against terrorism, a military statement said.
A military advance team began work in Maiduguri on Monday, the statement said, as part of plans to move the command and control centre from Abuja.
President Muhammadu Buhari took office last month, vowing to beat Boko Haram.
He announced that the military would move its headquarters to Maiduguri, in the north-eastern state of Borno, in his inaugural speech on 29 May.
The aim is to centralise operations close to the action, cut bureaucracy and speed up decision-making.
The policy and administrative arms of the military have been accused of being detached from the reality of the soldiers on the frontline.
For example, the complaints from troops about their inadequate supplies of equipment and poor welfare were often denied, downplayed or ignored by the authorities. This led to disgruntlement among soldiers, with some refusing to fight and even shooting at their own commanding officer.
However the relocation has not gone down well with some top military men, who have viewed it as merely a symbolic or even populist move, possibly driven by a desire to be distinctively different from the previous administration of former President Goodluck Jonathan.
There are also concerns it could further complicate existing operations on the ground.
