For now, the Russian military may be considering increasing the number of Arena-M counter munitions to intercept incoming drones and other projectiles. But as Euromaidan Press explained, space constraints for the turret-mounted projectile launchers could ultimately limit that approach.
Concerns beyond the war in Ukraine
The limitations of active protection systems against drones have also appeared beyond the battlefields in Ukraine during the US-Israeli war against Iran. When the Israeli military sent troops into Lebanon to fight the Iranian-backed faction Hezbollah, the Israeli Merkava 4 tanks came equipped with Trophy active protection systems developed by Israel’s Rafael Advanced Defense Systems.
But Hezbollah militants published multiple videos showing their small quadcopter drones loaded with explosives striking Israeli tanks that had Trophy systems still loaded with countermunitions, according to the Ukrainian media company Defense Express. Such videos implied that the Trophy system had difficulty detecting incoming small drones.
Making matters worse for the Israeli military, Hezbollah deployed drones that are immune to radio signal jamming because they are connected to human operators by miles of fiber optic cables. That battlefield innovation first came out of the war in Ukraine and became a crucial part of Hezbollah’s arsenal as the faction ramped up its asymmetric campaign against Israel between March and June 2026, according to the Institute for the Study of War.
Although it’s unclear how many Israeli tanks were damaged or knocked out by Hezbollah’s drones, such drone attacks became the top threat for the Israeli military in Lebanon and accounted for the majority of deaths among Israeli soldiers after a temporary ceasefire went into effect in April, The Wall Street Journal reported.
Despite uncertainty about the Trophy active protection system’s performance, multiple European countries have been buying the Trophy system in an attempt to better protect their tanks against the threat of drones. The EuroTrophy joint venture expects to equip 400 European Leopard tanks with the system, according to Breaking Defense.
The US military has already equipped several hundred M1 Abrams tanks with the Trophy system in recent years. But it’s clear that the United States and many other countries are still sorting out the best way to deploy tanks on drone-dominated battlefields. During the Combined Resolve military exercise held in Germany this year, Ukrainian drone operators wiped out an entire brigade of US Army tanks and armored vehicles.
