Not really. They no longer have an enemy to worry about, they’d have no need for any type of heavy armament beyond border defense. They already have more than enough small arms.
Otherwise they would have properly repaired and reused the massive amount of vehicles left behind by the USA (they did a few to show off).
They wanted to be left alone and they got their wish, which is why they don’t even bother to attempt with being recognized.
I think there was even a rumor that Mullah Omar kept the nation’s finances under his bed instead of a bank because it was that trivial of an issue for him.
