Instructors 

The Nigerian Forest Security Service (NFSS) has a leadership structure that includes various Deputy Commander Generals (DCGs) who oversee different bureaus. These individuals would likely be involved in training and instruction within the organization.

Based on the information available, some of the individuals holding positions that suggest an instructional or leadership role are:

 * Prof. Edwin C. Opara: DCG Community Service Bureau

 * Major Sunday Akpa (Rtd): DCG Patrol & Guard

 * Prof. Nelson Fashina: DCG Education

 * Major Dr. A. A. Muhammad (Rtd): DCG Training

 * Barr. Lawrence Okonkwo: DCG Administration

Additionally, ACG Haruna Umaru Hammanjoda Furo is mentioned as the Zonal Commander North-East zone and is involved in discussing the deployment and operations of hunters, implying a leadership and potentially instructional role in that region.

It's important to note that the NHFSS also has State Commanders, and the Commander General is Amb. (Dr.) Joshua Osatimehin. While these roles are leadership positions, the DCGs listed above seem more directly involved in the structure of training and education within the NHFSS.
