DARPA’s Ground X-Vehicle Technology program (GXV-T) initiative that could lead to an entirely new era of tanks and armored combat vehicles. GXV-T would offer tank-like protection on a vehicle that resembles a futuristic All-Terrain Vehicle (ATV) but is smaller than a traditional tank.
They are using augmented reality for windowless vehicles.
This will likely lead to a yuge paradigm shift by the 2040s or so. Though interestingly, it looks like it will still have a crew of 1. I'm sure that traditional tanks will increasingly find themselves threatened by drone swarms, so the sneakniess and speed of GXV-T will motivate advanced militaries to adopt it.
