According to Sahara Reporters, Lieutenant-Colonel Mamudu was killed along with a young Naval officer while on patrol for Operation Deep Punch 11.
Mamudu, described as a fearless fighter, hailed from Kogi state.
Military sources at the defense headquarters say this is his second time of his coming to Northeast. He was first posted to Borno in 2015.
He was posted there last year from the Nigerian Army HQ department of training and operations (DATOPS).
