The Israelis had GPS units placed in almost all of Hezbollah’s vehicles by a high-ranking Hezbollah official. Correspondent Mitchell Prothero tells the story in The National (UAE).
Now, if I just read that story in a random Persian Gulf paper, I would assume it’s fiction. But Andrew Exum vouches for Prothero, and interviewed him about the story. [Correction:] Prothero is a US Army veteran [journalist] with extensive experience [reporting on the US Army] in Iraq.
Israeli history buffs might say this kind of spy-work is Eli Cohen material.
