Land forces face a new revolution in military affairs based on three digital technologies: ubiquitous sensors, 5G networks and artificial intelligence. Soldier connectivity is a key enabler to tackle this revolution. High-speed, high volume data transmission, improved power management and wearability are essential for commanders to exploit new sensors, networks and AI applications. The armies that succeed in adopting three innovation practices seem most likely to realize the greatest advantage from the 21st century digital revolution in military affairs: 1. Optimize decision processes, not individual devices; 2 Design the soldier experience; 3. Make small bets as fast as possible.
