IDF troops mistakenly open fire on suspected drone in Golan Heights

"The Israel Defense Forces determined after the incident that no aircraft had crossed the border, however, and declared a return to normal routine.
It wasn’t immediately clear what had set off alarms.
In a similar incident, on August 21 soldiers opened fire at a crop-dusting plane flying over the Golan Heights, mistaking it for an infiltrating aircraft from Syria, in what the IDF called a “serious incident.”
The pilot was not injured."

So not only do they not know what they're shooting at, they can't even hit what they aim for. Don't these guys have the iron dome or something?
