Chief of Army Staff, Lt. Gen. Tukur Buratai revealed the decision on Thursday.
"The army has deployed about 3,000 officers and men, as well as equipment for the exercise. The number of personnel will be increased to 10,000 by next year."
On why "Operation Crocodile Tears" was necessary, Buratai said:
"...because the state is largely riverine and borders the Atlantic Ocean and therefore prone to external aggression, which we have to prevent."
