Drone warfare is example in of cutting edge technology. It doesn’t have to be hard electric technology, but the technology of how war is being waged. Using 100 of cheap small drones to stop air attacks from large drones instead of patriot missiles. Creating zones where the enemy can’t go it because of drone coverage. Wiping out a 3rd of a countries nuclear capabilities in one attack. Even while oil is at an all time high Russia can’t take advantage of it because Ukraine is destroying ports making it almost impossible to ship oil out.

You do realize that Ukraine has more cutting edge tech at the new way of war that the US. The EU is getting more weapons from Ukraine and they are building factories in the EU
