i saw one news report that said they trained them to use high tech surveillance and close air support - both of which are only provided by the US military. once the US military pulled back, afghans had to fight without those two advantages that they were trained for. the taliban, on the flipside, are experienced at fighting without that, so they do simple infantry fighting better than the puppet army we left. without an air force, the afghan army is doomed.
they have their own surveillance and close air support (both fixed and rotor-wing and have been actively using it….. probably HAD, at this point. They aren’t “losing” battles in the sense we know. They’re quitting to go be with their families.
