Obviously.

We will have a lot to learn from this war when it’s done. It’s the first war in a while were two developed countries fight eachother.

No country has “avoid getting a grenade dropped by a drone into your trench” in their training program. But they will have to after this war.

The instructors should adjust the training after every course if the Ukrainian officers advice them too. If they don’t they fail as instructors.

What the west could provide early on is to relieve the Ukrainian army with a lot of the training so they could focus on this new threat. As they have.
