@pony you are probably not following the RU-UK Donbas conflict too much, do you? It was back to WW2: two parties throwing tons of steel to each other. No air force involved, suddenly high quality anti-tank tech is **the** major tech advantage.
We always thought the next big war will be all air force, satellites, etc. Maybe not. Maybe it will be a throwback to WW2 again for some important reasons.
@pony Next time I speak to a land army officer I need to ask them about this. Some interesting and non-obvious developments are happening where I have a chance to look at. For instance the Dutch army by the end of 2010-ish abandoned all tanks. So there are none left. The idea back then was that 1) there is no immediate threat of a conventional war; 2) it's an outdated concept; and 3) there's a need for a more flexible special-ops force mix. Then 2014 and Donbas conflict came and the NLD land army woke up to a new reality and started to consider reintroducing tanks back - at a great cost as the knowledge and skills are being lost. Mind you, those tanks are not getting back yet, some smarter ideas came along, but the dynamics is in itself quite interesting.
