Business Insider:
Just before the end of January, Russia announced that its Pantsir-S1 mobile surface-to-air missile and anti-aircraft artillery weapons system would be equipped with a new type of missile to help it defend against smaller, low-flying targets.
Called the “gvozd” (the Russian word for “nail”), the missile is a small armament designed to take out small targets like drones. The Pantsir will reportedly be able to carry 4 gvozds in one canister, which means a fully armed system can have up to 48 missiles.
The issue of how to combat small and cheap drones that can carry small payloads or carry out kamikaze-style attacks continues to vex global militaries. The terrorist group ISIS has found them to be particularly useful, and last January saw a swarm of drones attack a Russian air base in Syria, reportedly damaging seven jets.
