Do you have to enlist first to apply for Warrant Officer Flight school?

I was doing Research I did see anything about enlisted before you apply however, you most likely will have too because you need at lease 3 letter of recommendation from an Army Aviator in the rank of CW3 to CW5 or Major and above and that a minimum requirement. I don't think anyone will give you a recommendation unless you are in the military. So the would be yes you need to enlist in the military First. Having a college will definitely give you an edge.
