Source? To my knowledge, we’re not sending anything newer than the Iraq War to Ukraine. That means decent missiles but crappy drones.

US is sending all sorts of gear, not just dusty stuff from the back of the shelf. Sure, there would be reapers, but also modern stuff from switchblade drones (in use since 2010) to Phoenix Ghost (designed a couple of years ago).

one way this war has been calamitous for Russia as it has shown NATO how unprepared they are for Russian electronic countermeasures. Let’s see if NATO can learn and adapt in time.

Not sure what specific drones have been sent, but we're definitely sending stuff newer than the Iraq War; heck, Ukraine has received the newly-developed GLSDB before US forces got it for other-than-testing use.

And in real combat it turns out that the Russians have easily suppressed them with GPS jamming. Also the steerable artillery.

It’s useful to the US to learn this before they try to depend on it in combat themselves. They’re going to have to switch to vision.

US doctrine involves SEAD and immediately obtaining overwhelming air superiority, not being confined to the ground or artillery duels.

Look no further than day 1 and 2 of Desert Storm - Ukraine hasn't mounted an operation even remotely resembling the scale or complexity (and can't.)
