Bad Headlines
That’s the rondel/emblem identifying equipment belonging to the Afghan National Army & Air Force.
The headline: NBC News finds abandoned U.S. military equipment at Kabul airport for a video report is wrong. The equipment belongs to Afghan Forces, not the US, and not all of it was built in the US. The correspondent makes it clear this was not US military equipment and that it was disabled.
Apparently headline writers at NBC aren’t required to look at the videos or articles before creating their headlines.
