The Russian Armed Forces ferreted out a Ukrainian self-propelled artillery system 2S1 Gvozdika and destroyed it with a high-precision munition.
A loitering munition, commonly referred to as a kamikaze drone or a suicide drone, is more than just a projectile, but not quite a regular UAV. This weapon by definition can loiter, or passively wait in a target area, looking for its prey and attack when the target is pinpointed.
Such munitions make it possible to carry out a powerful surprise attack, and moreover, kamikaze drones are capable of selective targeting – meaning that the attack can be aborted or re-directed during flight.
Technically speaking, loitering munitions fill in the niche between cruise missiles and military UAVs. The ability to lie in wait for a target is what makes them superior to cruise missiles. Nevertheless, they are called suicide drones for a reason – they have a built-in warhead, and they don't survive an attack. However, they are much cheaper than regular combat UAVs.
