Photos have been circulating showing Taliban fighters holding U.S.-made M4 and M16 rifles instead of the Russian AK-47s they normally use. Militants have also been spotted using driving U.S. Humvees and mine-resistant ambush-protected (MRAP) vehicles.
In addition, the Taliban is also reported to have seized Black Hawk helicopters and A-29 Super Tucano aircraft.
"Everything that hasn't been destroyed is the Taliban's now," said one U.S. official to Reuters on the condition of anonymity.
While it's nearly impossible to operate advanced aircraft, such as those left behind in Afghanistan, without training, the seizing of the hardware gives the Taliban a propaganda boost. In addition, it also underscores the amount of money wasted on U.S. military efforts in Afghanistan over the past 20 years.

"When an armed group gets their hands on American-made weaponry, it's sort of a status symbol. It's a psychological win," explained Elias Yousif, deputy director of the Center for International Policy’s Security Assistance Monitor.
"Clearly, this is an indictment of the U.S. security cooperation enterprise broadly," Yousif added. "It really should raise a lot of concerns about what is the wider enterprise that is going on every single day, whether that's in the Middle East, Sub-Saharan Africa, East Asia."
According to a 2017 Government Accountability Office report, the United States transferred 75,898 vehicles, 599,690 weapons, 162,643 pieces of communications equipment, 208 aircraft, as well as 16,191 pieces of intelligence, surveillance and reconnaissance equipment to Afghan forces between 2003 and 2016.
Meanwhile, a report from the Special Inspector General for Afghanistan Reconstruction (SIGAR) states that the U.S. also gave Afghan forces 7,035 machine guns, 4,702 Humvees, 20,040 hand grenades, 2,520 bombs and 1,394 grenade launchers from 2017 to 2019 alone.
The SIGAR report also confirmed that Afghan forces had 211 U.S.-supplied aircraft in their inventory as of June 30. Of these, at least 46 are now in Uzbekistan after more than 500 Afghan troops used them to flee the country.
Exactly how much U.S. weaponry has fallen into the hands of the Taliban is unknown. That said, the Biden administration has acknowledged that it's a "fair amount."
"We don't have a complete picture, obviously, of where every article of defense materials has gone, but certainly a fair amount of it has fallen into the hands of the Taliban," said White House national security adviser Jake Sullivan on Tuesday, Aug. 17. "And obviously, we don't have a sense that they are going to readily hand it over to us at the airport."
With large numbers of U.S. equipment now in Taliban hands, concerns are now being raised over how they'll be used.
Both current and former U.S. officials have raised fears that they'll be used to kill civilians or be seized by other militant groups, such as the Islamic State, to attack U.S.-interests in the region. Worse, they could even potentially be handed over to U.S. adversaries including China and Russia.
The Biden administration is so concerned about the weapons that it's now weighing a number of options it may pursue.
Officials have stated that launching airstrikes against some of the larger equipment, such as helicopters, has not been ruled out. However, there are concerns that such strikes would antagonize the Taliban at a time where the U.S.'s main goal is evacuating people.
Others have pointed out that some of the larger equipment, such as helicopters, require frequent maintenance and are too complicated to fly without extensive training.
"Ironically, the fact that our equipment breaks down so often is a life-saver here," one official said.
Such equipment would be used more as trophies and propaganda boosters.
"But the time has passed for these efforts to have any impact in Afghanistan," she concluded.
