I don’t know much about the military, but I am very familiar with the marching arts. Discerning between two different tempos and keeping your feet in time with only one of them is a lot harder than it sounds. Unless there is time allotted to learning that skill specifically, I doubt any group of soldiers are going to do it flawlessly.

They may not fall apart, but its not going to look pretty. And apparently, it didn’t. If every soldier is capable of doing this, then why is there a whole post about how badly they did it?
