Facing the Threat: Drone Defence Doctrine
By John Hill | Global Defence Technology | March 10, 2026
As reported by Global Defence Technology on March 10, 2026, in the magazine's Spring 2026 cover feature on the evolving European doctrine for short-range drone defence, the ARBEL fire-control system has been profiled as one of the technologies reshaping what an individual soldier can actually do when a small UAS gets through the outer layers and bears down on him personally.
The feature, written by John Hill, opens with a hard observation about the present state of soldier-level counter-drone capability: there is almost nothing. When confronted by an attacking UAS, a soldier's options today are uncomfortably narrow, run, hide, fire blindly, or, in some recorded cases, simply freeze in place. The Russian and Ukrainian experiences cited in the article underline how unforgiving this gap has become; tactics on the eastern front have included motorcycles and quadbikes used to outrun drones, and even cases of human-bait improvisation by troops with no better answer. The doctrinal void is what ARBEL is built to fill.
The framing the article offers for that build is striking. Just as helmets and the bulletproof vest emerged decades ago as the soldier's basic protection against incoming fire, modern infantry now need an equivalent answer to the drone, and the proposition behind ARBEL is that the answer is to intercept the drone with your own ammunition rather than wait for a dedicated counter-UAS system to handle the engagement at distance. In other words: the rifle the soldier already carries should become the close-in interceptor.
Mechanically, ARBEL is described as an AI-powered fire-control system designed to enhance small-arms accuracy, with a particular emphasis on moving UAS targets. The computerised system is integrated directly into the pistol grip of any standard AR-15 rifle, meaning the host weapon stays familiar and unchanged in handling. ARBEL's sensors monitor the shooter's behaviour in real time, weapon movement, trigger status, and use those inputs to calculate the optimal micro-moment for each shot. The user experience that emerges is a striking simplification of a difficult engagement: the shooter holds down the trigger, and the system itself selects the moment of release that gives the highest probability of a hit on the moving aerial target. Aiming, stabilising, and timing, three skills that, in an unscripted drone engagement, normally have to align perfectly under extreme time pressure, are collapsed into a single, machine-mediated trigger pull.
The strategic implication threaded through the article is that close-in C-UAS is no longer a niche capability but a core layer of the emerging air-defence architecture, sitting alongside short-range missile interceptors and area-defence concepts at the squad and platoon tier. ARBEL represents the soldier-tier answer in that stack: an AI-augmented standard rifle, ready in the hands a unit already has, calibrated for exactly the kind of fleeting low-altitude target that has come to define modern combat.
