NATO has been developing the concept of Strike/Stryker brigades as their main meat for a long time
And how is that working out?
From what we can see they’re less effective as breakthrough weapons and more as short-range, direct fire, mobile artillery
Preeeetty sure they've stopped being the main breakthrough force since WW1. Cracking enemy defenses is artillery's job. Tanks are cavalry - exploiting the breach to speed towards the soft stuff at the rear. Fuel storages, depots, the works.
If anything, Ukraine war and the aforementioned extensive usage of drones just goes to show that artillery is still king.
