Marines Receive New Anti-Drone Ammunition for M4 and M27 Rifles

The United States Marine Corps has begun equipping its forces with a new type of ammunition designed to counter small drones. This specialized round can be fired from both M4 carbines and M27 Infantry Automatic Rifles, providing Marines with an enhanced capability to neutralize aerial threats. The Drone Round 5.56 L Variant separates into five distinct projectiles upon firing, increasing the likelihood of hitting fast-moving targets like reconnaissance and attack drones.

According to a Marine Corps acquisition spokesperson, the service has already procured 400,000 rounds and plans to purchase an additional one million cartridges in fiscal year 2027. Deliveries have started at ammunition supply points across various units and are expected to be completed by September of this year. The decision on which Marine Expeditionary Force units will receive the anti-drone round first rests with their respective commanders.

The development and procurement of this new ammunition reflect a growing concern within the military regarding the proliferation of small drones used in combat scenarios. These unmanned aerial vehicles pose significant threats to ground forces, capable of conducting surveillance or launching attacks without being detected by traditional defense systems. The Marine Corps tested the anti-drone round extensively before fielding it, ensuring that it meets operational requirements and can effectively disable or destroy smaller drones.

While the Marines are at the forefront of adopting this technology, other branches have also shown interest in similar solutions. In April 2026, soldiers from the 18th Airborne Corps tested the anti-drone round against small drones during exercises at Fort Bragg, North Carolina. This cross-branch collaboration highlights a broader military initiative to develop and integrate advanced countermeasures against drone threats.

The introduction of this new ammunition marks an important step in enhancing ground forces' capabilities to operate effectively in modern warfare environments where unmanned aerial vehicles are increasingly prevalent. As technology advances, the military continues to adapt by integrating innovative solutions that provide tactical advantages on the battlefield. The deployment of these rounds underscores the ongoing evolution of combat tactics and equipment designed to address emerging threats posed by drone technologies.

This new capability not only bolsters defensive measures but also demonstrates the U.S. military's commitment to staying ahead in technological advancements, ensuring readiness for future conflicts where drones may play a more significant role.
