Drones all the way, they go through roughly 1 million a year and this number keeps increasing as time goes.

Artillery was more decisive till cca 2023 when switch to new warfare model happened. Its still important, but not #1. You have (ukraine-made since US switchblades proved inefficient overpriced piece of shit) drones now that have 2-3x the reach, can carry same/bigger payload, steer them till last second, some can come back home for reload. Drone teams are much smaller and more agile compared to artillery, they can drive around in normal SUVs.

Uh it's definitely drones right now. Artillery is < 10% of casualties at this point, the kill zone is close to 20km.

They're using what they have but the remaining pieces will clearly be mostly irrelevant by next year.
