Sometimes you stumble upon something bad — and it turns out being very, very good.

That’s what happened to a unit of British SAS (Special Air Service) soldiers who, by chance, realized that they were witnessing a transport of ISIS (Islamic State, IS, ISIL, Daesh) fuel tankers, being carried out by their jihadi fighters, and they pounced on them with an effectiveness the coalition hasn’t yet seen in their collective operation to rid from the globe.

The United Kingdom’s special force used grenade launchers (500 grenades total) and machine guns to completely destroy 20 ISIS vehicles — and kill more than 30 of their sworn terrorists in Syria.

According to eyewitnesses, the terror org’s entire motorized cavalcade went up in flames after being bombarded by the British troops and their immense showing of firepower.

Our source said: “It was like a turkey shoot.

The grenades ripped into the vehicle, exploding on impact.

“The terrorists dismounted from their vehicles and began to put up a bit of a fight but their resistance didn’t last long.

“The grenade launcher is one of the most powerful pieces of equipment in the SAS arsenal.

Numerous reports have estimated that there are at least 200 SAS troops roaming Syria while stationed near the Jordanian border.
