From my experience, very few people seem to know about this so I wanted to introduce you all to Arizona Cyber Warfare Range. According to their website, "We are a 24×7 live fire cyber warfare range. Our purpose is to develop a continuous improvement process for cyber warfare and security. We host live fire exercises for beginners through real world operations. Each area is designed to meet the needs of the students education level. With capability for upward progression into the real world of cyber warfare."
It's a pretty dope site so check it out!
*You have to sign up using your cell phone and it is an Arizona area-code phone number.
