modern army don't fight in a conventional way, it will be fought with drone, unmanned device, weapon, or equipment, (eg robot dog, wolf, etc ...)
another interesting observation at the front line, the army is using electric cyclist to infiltrate behind enemy location as these cyclist is very quite compared to the gas power cyclist. The BYD e6 and Xpeng P7 are the two well known model from China. They offer silent operation and are ideal for quick and effective deployment.
