Those Wacky Revolutionary Guards

I figure it's gotta be a translation error, but check out this article on a statement by an Iranian Revolutionary Guards "commander":
"We have built birds without passengers [drones] that can carry out suicide operations on the US Navy, at any depth if necessary, to make them leave the region in disgrace," said Ali Shoushtari, deputy commander of the Guards' land forces.
So the drones don't have passengers, but they're conducting suicide operations? How do they do that? Does the remote drone operator have to kill himself in his command center after the drone hits? Do they think the drones themselves are alive? Or do the Iranians just realize that if they use radio waves to control a drone we'll be able to take out the source of the transmissions fairly rapidly?
