How Hamas Disabled the Fence: Commercial Drones and Improvised Charges in the First Minutes of October 7

In the opening minutes of the assault Hamas launched on the morning of Saturday, October 7, the group's operatives flew commercial quadcopter drones, some described as DJI models or DJI-based variants, fitted with improvised explosive charges. The drones were guided with precision toward observation posts, remote-controlled weapons stations, cameras, and generators powering communications infrastructure along the Gaza border fence, in an operation reportedly referred to inside the organization as the 'blinding plan.'

A coordinated strike across dozens of points along the fence

According to reports in Israeli media and assessments from security officials, the operation was neither random nor isolated. It was a coordinated wave of strikes aimed at disabling, as quickly as possible, the technological defense layer Israel had relied on along the fence, just minutes before Hamas operatives physically breached it using ATVs, explosives, and bulldozers.

• Estimated start time: around 6:30 a.m., October 7, 2023
• Type of equipment: commercial quadcopters, some DJI models or derivatives
• Targets of the strikes: observation posts, remote-controlled weapons stations, security cameras, generators for communications infrastructure
• Reported scope: strikes at dozens of points along the border fence
• Exact number of drones and charges: not officially confirmed, figures vary between reports

An expensive defense system that proved vulnerable

Until just weeks earlier, the Gaza border fence was considered one of the most advanced and expensive defense systems Israel had ever built, equipped with sensors, cameras, remote-controlled weapons stations, and extensive communications connectivity. But Israeli analysts and commentators note that this infrastructure relied heavily on a chain of components that, if severed at a few critical links, could bring the entire system crashing down like a house of cards. A remote-controlled weapons station without a working camera or active communications is effectively a dead post.

This gap between the cost of defense and the cost of attack is fueling the main criticism now dominating security discourse. A commercial drone with an improvised charge costs a few hundred to a few thousand shekels, compared with a defense system estimated to cost billions. The disparity echoes similar strikes documented in the Russia-Ukraine war, where cheap drones have reshaped the battlefield against far more sophisticated armored and artillery equipment.

What remains unknown

At this stage there is no official, confirmed count of how many drones were deployed, how many points were actually hit, or the exact time that elapsed between the initial disabling of defenses and the actual breach of the fence. Some reports point to precise advance planning designed to exploit specific weak points in the Israeli system, raising difficult questions about how field intelligence and surveillance failed to detect the scale of these preparations beforehand.

Security officials are currently also examining whether Counter-UAS detection and jamming systems present in the area were operating in real time, and if so, why they failed to stop the attack. As of this article's publication, the IDF has not issued an official, detailed response outlining the precise sequence of events at each of the affected points.
