The new multinational force had gotten up and running in November, he said, adding that most of the soldiers belonged to the BIR — “among the best troops in Cameroon.” But other sources told me that the multinational force had been beset by internal feuding. The Nigerian military was demanding a leadership role, and the Chadians and Cameroonians were resisting. The feuding had slowed the integration of the three nations’ soldiers into a single unit; the “multinational force” along Cameroon’s border, for example, was still almost entirely made up of Cameroonians, and by the time I caught up with the officer in mid-January, it had made only four brief incursions into Nigeria.
