Military
On the ground there's a ceremony where everyone keeps stopping. This stopping ceremony is being performed by the military. They'll march one direction, then stop and turn, then march another direction, then stop again.
The military really seems to have a thing for stopping a lot during their ceremonies.
ぶ, む
たけ
None
You look closer at the people in the military and realize that every time they stop they take a drink of booze (ぶ)!
This is a ceremony for celebrating the military so I guess they can drink as much booze as they want, but this seems very strange to you.
