Ukrainians used some tractors in the early stages of the war, for logistics and troop carrying. Finnish Defence Forces are famous (or infamous) for relying a lot on tractors for war-time mobility of troops.

The question is, why haven't we seen more use of tractors being used in Ukraine by both sides? They offer off-road mobility and versatility that most trucks aren't capable of. And both countries have national production lines for tractors.

I have been following Project 171 in YT. Of course, the makers are not exactly your normal DIYers: they are uni professionals who have done their lifework with vehicle design and dynamics, and use advanced computer modeling as they go.

But, when they talked about aerodynamics, and how CFD is nice to have but not important, I thought: how well can you get aerodynamics right just by feel? Or other way around: if I design a car just by looks, what I think is aerodynamic, how much of a change there is it's anywhere near aerodynamic? Back in the day they thought a teardrop shape is the most aerodynamic, or a wing (apparently causing a bit of problem with lift, well, because obviously).
