Background. The ANG operational training infrastructure (OTI) enterprise requires realistic, standardized, full spectrum, and immersive data link and secure voice communication systems. The ANG continues to have shortfalls in standardized communication and data link systems at the critical nodes of the range training infrastructure. The OTI enterprise consists of the flying squadrons, primary training ranges, live mission operations capability centers, training centers, and forward operating locations. Acquisition of advanced radio over internet protocol management systems, Link 16, situational advanced data link (SADL), secure range communications, and a training data link management system with man-in-the-loop data input capability will enhance ANG units’ ability to accomplish realistic full-spectrum, multi-domain training. The ANG requires communication upgrades for four Combat Readiness Training Centers (CRTCs), 11 Primary Training Ranges (4 co-located with CRTCs), and 23 fighter wings.
