What I'm hearing from the guys in theatre is we left pretty much nothing US owned in working condition. It either was straight up the ANA's, or it met the demil requirements for transfer to the ANA, and we transferred it, or we destroyed it in place. That also tracks with what I saw last year when I was deployed. We started moving the big and important stuff out in mid 2019, and rigged everything else for a quick withdrawal. Things you're seeing on the internet like those drones (Scan Eagles) are the ANA's stuff. The Blackhawks I've seen are all ANAF UH-60A's. (We fly -60L's) the MRAPS I've seen don't have any of the antenna's that would indicate our force tracking or digital battlefield capabilities, or even 3rd Gen NV/Thermal. One guy told me they went as far as slashing the fuel bags in the FOB's if the ANA didn't/couldn't take them before they left. All the stuff at Bagram we heard about (Toyotas, HMMWV's, small arms, ammo, and the like) was stuff we were directed to turn over to the ANA, so export model or lower. Don't get me wrong, a lot of it was nicer then the Soviet surplus the Taliban had before, and I'm seeing a lot of M4 w/ACOG on the news, but it's not current, or even last, gen US gear.
One of my emails actually said the feeling back in Kuwait (where most of this stuff went for sorting) is that the military did a pretty solid, by the book deliberate withdrawal, took our stuff and disabled what we couldn't, got all of our personnel out (minus the 'terps, but we did what we could there) and got to the airport, looked at the State Dep and USAID folks and said "What do you mean you left people out there? Didn't you see us leaving?"
Bear in mind my friends and I are talking on unclass e-mail, so there maybe a few missed things they aren't trumpeting to the world, but not tons and tons of hi-tech gear.
YMMV.
