Understanding NIS Symbols and Insignia

Each rank has a specific insignia—usually worn on the shoulder or chest area. These symbols not only identify an officer’s authority but also their duties and responsibilities.

The symbol system follows international paramilitary standards but is uniquely designed with the NIS color palette—usually gold, green, and black.

How to Recognize Officers by Rank

When interacting with an officer, especially during recruitment or verification procedures, it helps to know their rank and authority. This can prevent you from being scammed or misinformed.

For example:

ACGs and DCGs work mostly in Abuja and state headquarters.
Comptrollers run state commands.
Assistants and Inspectors are commonly seen during border or airport operations.
