group of people in uniform saluting in what appears to be a military-style ceremony

group of people in uniform saluting in what appears to be a military-style ceremony. Some are wearing red jackets with black pants, while others are in black or green military-style uniforms. There are two flags visible, one is the Nigerian flag, and the other is a darker green, yellow and black flag. They are standing on a wet concrete ground, reflecting the cloudy sky. In the background, there is a crowd of people watching and some buildings. The video is being taken by someone holding a phone, whose hand is visible at the bottom of the screen.
