The unit, the Rapid Intervention Brigade, is at the forefront of Cameroon's fight with the Nigeria-based Boko Haram militants in the north-west.
In a statement, Timothy Antigha, spokesman of 8 task force division, Borno state, quoted Stevenson Olabanji, the division's general officer commanding (GOC), as saying this when he visited troops of the 118 task force battalion under the division.
Mr. Olabanji, a brigadier general, asked the soldiers to always make sure their weapons are serviceable as the strike order on the secret Boko Haram location could be given at any time.
He added that the final phase of the operation to dislodge the remnants of Boko Haram terrorists who are still operating in remote islands within the Lake Chad Basin is in the offing.
The primary Boko Haram base in the Sambisa Forest was cleared previous year by the army, but the group has successfully launched deadly attacks in Borno state.
Responding, the personal assistant to President Muhammadu Buhari on new media, Bashir Ahmad, said Nigerian troops are on their way to the location.
A witness, Grema Bana, said that the incident occurred at about 4:45 p.m., at one of the pastoralist hamlets in the area.
