Telluric Group has been the nation's leading provider of night vision training for more than a decade. We've trained elite military personnel and thousands of federal, state, and local law enforcement officers. Our courses are NOT gear-centric. Gear obviously plays a central role in low light (and particularly NV) operations, and we do cover equipment set-up and use. The focus of our courses, though, is principles [1st] - tactics and techniques [2nd] - and then gear [3rd].
