A convoy of ISIS-owned fuel tankers burn after being targeted by a Russian airstrike.

In one fell swoop, a series of aerial strafing and bombing runs destroyed 83 oil tankers belonging to ISIS forces in Syria.

USA TODAY reports that after a pilot witnessed a gaggle of vehicles in the oil-rich, ISIS-held region of Deir ez-Zor province, US-led coalition forces sent a surveillance aircraft to provide intelligence on the area. After confirming the targets, A-10s and F-16s were scrambled to dispense more than 80 munitions against the vehicles.

After the dust settled, an estimated $11 million worth of oil and trucks were destroyed in the largest single airstrike against ISIS forces in Syria this year.

"You're going to have multiple effects from this one strike," said Air Force commander Lt. Gen. Jeffrey Harrigian.

The vehicles, which were reported to have been out in the open, may be indicative of the declining state of ISIS' leadership and control. After a series of devastating airstrikes from both coalition and Russian forces, ISIS militants have grown accustomed to evade aerial threats by avoiding traveling in large convoys; however, this latest lapse in judgment could be a sign of worse things to come for the militants.

"This is a very good indication that they're having trouble commanding and controlling their forces," Harrigian explained to USA TODAY.

The bombing campaign, otherwise known as Tidal Wave II, was enacted to wipe out ISIS' oil market that was generating more than $1 million a day during its peak.

At the beginning of this operation, coalition aircraft would drop leaflets on the oil tankers prior to their bombing runs to provide the option for drivers to escape. However, after new military rules were implemented, leaflets are no longer required to be dropped.

Instead, pilots are now firing warning shots to indicate their arrival.
