What are the criteria for becoming a Warrant Officer? Is a college degree required?

For most MOSs no but it is strongly recommended to pursue a degree to remain competitive for promotion especially as a senior warrant. A Warrant Officer in your desired field or your Warrant Officer recruiter can provide you with the necessary prerequisites

Prerequisites vary. College degree NOT required because we're too cool for that lol Why the question? You trying to become one?

At least one Warrant I knew had no college degree, the other two I knew did, one was a PA.
