The Taliban’s newfound American arsenal is likely not limited to small arms, as the group captured sizable stockpiles of weapons and vehicles held at strongholds once controlled by US-backed forces, including modern mine-resistant vehicles (MRAPs) and Humvees.

Initial estimates suggest the Taliban may now also possess several Black Hawk helicopters and other US-funded military aircraft, according to a congressional source familiar with early assessments provided by defense officials.

That potentially includes roughly 20 A-29 Tucano attack planes, the source said, noting there are some indications that only a small number of aircraft were relocated from a base in Kandahar before it was overrun by the Taliban.
