Marines Used Anti-Drone Netting During Recent Logistics Exercise
Faced with the ubiquitous threat from small attack drones, military forces around the world are resorting to the use of large amounts of mesh netting for protection, something TWZ was among the first to highlight. Now it appears the U.S. Marine Corps may be employing this defensive measure as well.
After a recent logistics training exercise in South Korea, photographs were posted on the Pentagon’s image distribution site showing what appears to be anti-drone netting on a ship-to-shore floating platform used for moving cargo and troops. While it’s possible that it could be for some other purpose, the netting appears to be in line with other examples of drone defensive measures seen in Ukraine and many other places, including recent usage by Dutch forces. We’ve reached out to the Marines for more details.
The idea behind the netting, as we have reported in the past, is that drones will get caught up in the nylon or mesh metal nets and become disabled, or the nets will help keep the drones far enough from personnel before exploding to keep them from being killed. How protective the netting set up by the Marines would be against highly maneuverable first-person view (FPV) drones is questionable, given how open it is on both ends, though it could provide some protection from lighter munitions dropped by so-called bomber drones. Beyond that, the netting only covers one section of the floating platform, presumably where the cargo or a vehicle will go, leaving the rest of it, as well as the ship and its wheelhouse, fully exposed.
The images were taken during Combined Joint Logistics Over-the-Shore 26 (CJLOTS 26) at Dogu Beach, Pohang, South Korea on July 9. The goal of CJLOTS 26 was to allow the Marines and partners from the Republic of Korea’s military to deliver supplies from a vessel stationed offshore without requiring existing infrastructure like a pier.
“The offload was a Maritime Prepositioning Force exercise where 3rd Marine Logistics Group (MLG) distributes equipment from a created port of entry and provides support to III Marine Expeditionary Force units training throughout South Korea, testing and validating 3rd MLG’s ability to conduct integrated logistics operations in complex environments,” the Marines noted. “CJLOTS 26 is a combined exercise designed to integrate U.S. and Republic of Korea lighterage and ship-to-shore connector capabilities, improve combined readiness, strengthen the Republic of Korea-U.S. alliance, and expand combined maritime sustainment capacity during logistics operations.”
The images show Republic of Korea service members aboard an Improved Navy Lighterage System (INLS), “a sea state three (SS3) capable causeway system that resembles a floating pier comprised of interchangeable modules and is used to transfer cargo from Military Sealift Command (MSC) ships to shore areas where conventional port facilities are unavailable or inadequate,” according to the Navy.
The troops were conducting what is called a “beach stabbing,” where the module is attached to the beach so that vehicles and troops can come ashore.
You can see another example of the INLS system in the following photograph taken in 2022.
While the Marines don’t specifically mention drone defense in photos, U.S. Forces Korea/Combined Forces Command did explain it was part of a large-scale training exercise designed with the drone threat in mind.
“To enhance full-domain operational sustainment capabilities, the exercise integrated five types of ground, maritime and air sustainment assets,” according to U.S. Forces Korea/Combined Forces Command. “Reflecting evolving battlefield conditions, the training also strengthened protection measures for sustainment nodes against threats such as hostile drone attacks.”
There’s good reason for counter-drone efforts to be baked into logistics operations. The war in Ukraine has shown that drone attacks have made resupplying front line troops such a deadly endeavor that there is an increasing use of ground robots to carry out these missions.

Any fight against China or North Korea would almost assuredly see large numbers of drones descending on U.S. and allied forces. Both countries have developed large arsenals of these weapons and the technology to use them at scale. North Korea, as we have reported in the past, has gotten assistance from Russia on drone technology as well as direct experiencing fighting Ukraine. The regime has invested significant resources into evolving its drone capabilities across all tiers.
Amphibious operations are especially vulnerable to short-range drone attacks. Approaching over the horizon in open water to a controlled beach means commanders can assume their assets will be attacked by FPV and other short-range drone types, and likely at scale.
The extent and effectiveness of netting that would be deployed as a passive defensive measure in future battles is an open question; however, U.S. military doctrine is starting to acknowledge the need. Newly released guidance from the Pentagon suggests using such systems as part of a layered defense against small drones.
“Two proven ways to disrupt drones are shaping their physical environment and interfering with their signals,” according to a new handbook published by the Pentagon’s Joint Interagency Task Force 401. “Obstacles such as fencing, netting, or over-head structures can alter flight paths, block common avenues of approach, and push drones into visible or unfavorable routes while also degrading control links, GPS (Global Positioning Systems), or navigation timing.”
The Pentagon established JIATF 401 last August to coordinate counter-drone efforts across the department and help accelerate the fielding of new capabilities. The guidance in the handbook follows a call in February by the task force for the increased use of netting, cables, and other kinds of passive physical defenses to protect critical infrastructure. It is part of an evolving trend by the U.S. toward acceptance of these measures, something we discussed in great detail here.
In addition, as we reported two years ago, U.S. Air Force officials at Langley Air Force Base in Virginia were looking at installing anti-drone nets to help protect F-22 Raptor stealth fighters on the flightline. That came nearly a year after the base was subjected to waves of still-mysterious drone incursions, which The War Zone was first to report.
Still, despite JIATF 401’s suggestions about netting and the Air Force’s interest in installing it to protect prized aircraft, there is scant evidence of widespread use by the U.S. military, leaving it lagging as these measures proliferate around the globe.
As we noted earlier in this piece, TWZ has showcased examples of netting use beyond Ukraine. The most recent instances emerged in Lebanon, where Israeli troops began using netting to protect against increasing attacks from Hezbollah FPV drones. The netting was erected after Israeli military leaders were heavily criticized for not doing enough to protect their troops from drone attacks. In fact, some Israeli troops were so desperate to get netting they reached out to fisherman.
The following video shows one example of Israel’s use of anti-drone netting.
Elsewhere, we reported that Taiwan is using anti-drone netting to protect its air defense systems. There are also reports published in the Netherlands that Dutch troops trained using anti-drone “net tunnels” – similar to those used by Russia and Ukraine – during an exercise in Germany last month called “Fighter Lion.”
Whether the netting seen in the logistics training exercise in South Korea represents a trend, or a one-off experiment, is currently unknown. However, one thing is clear. Netting, while certainly no panacea, is increasingly viewed as a critical countermeasure for militaries across the globe.
