I still chuckle about the "highly trained" Iranian operative who was caught making bombs destined for Israeli tourists in Thailand when one of them detonated prematurely blowing the roof off the house he was living in. He emerged into the street covered in blood and with his trousers ripped off and flagged down a passing taxi. When said taxi saw him up close it sped off and the enraged operative proceeded to throw a grenade at it, he then also threw a grenade at arriving police officers only to have it bounce back off a tree and blow his legs off.
Not exactly SAS material.
