Maybe portable anti-aircraft guns abandoned in Bagram.
Maybe.
At any rate, apparently there's an emergency meeting going on right now in the White House with Trump, all the National defense cabinet secretaries and military senior brass, and the intelligence agency heads.
Trump seems to be at a decision point, after the events over the past few days.
His options:
1) Escalate further and take Kharg Island and those in the Strait using the USMC.
2) Drop the 82nd Airborne onto Iran's Strait-side coastal pocket to form a defensive perimeter there and re-open Hormuz.
3) Drop the 82nd Airborne deep into Iran, along with U.S. SpecOps, to seize and remove Iran's nuclear material.
4) Declare victory and bring the troops, sailors, and airmen home.
5) Nuke Iran.
6) All of the above.
