Qiam-1 short-range ballistic missile.
Qiam missiles, which have a range of 435—497 miles and a payload of 1,653 pounds, have been in Iranian service since 2017.
The Houthis, who control Yemen’s capital Sanaa, have fired dozens of missiles into Saudi Arabia in recent months, part of a three-year-old conflict that is a proxy battle between Saudi Arabia and Iran.
Sayyad-2 surface-to-air missile.
Unveiled in 2011, Sayyad-2 missiles have a range 48-62 miles and a payload of approximately 441 pounds.
The US said the “Sayyad-2” surface-to-air missile above had been interdicted by the Saudi government in early 2018 on the way to Houthi militants in Yemen.
Qasef-1 drone.
Qasef-1s are low-tech drones that can be used for surveillance or fitted with explosives, but the Houthis may have used them as kamikaze vehicles to damage radars for Saudi Arabia's Patriot missile defense systems.
Shahed-123 unmanned aerial vehicle.
The Shahed-123's specifications are murky, but it's likely an older model of a Shahed-129, which is a medium-altitude, long-endurance surveillance and strike drone.
KL-7.62 rifles.
KL-7.62 rifles are Iranian copies of Chinese Type 56 rifles, which are themselves copies of Russian AK-47s.
107mm Fadjr rockets.
The US said Iran gave the 107mm rockets seen on the left to the Taliban because of the unique markings on the rockets and the paint scheme, along with the markings on them.
The US has also long accused Iran of providing weapons to Taliban militants in Afghanistan.
The Taliban is known to buy weapons on the black market and defense officials could not say why they were sure these missiles and other weapons had not been simply bought by the militants.
