Rail charges, which functioned as ammunition for Rail Detonators, were essentially small explosive devices. These charges were not only highly explosive, but they also adhered to the surface they struck for a short duration prior to detonation, potentially eliminating a larger number of targets than initially aimed for.
The explosive capacity of this weapon was significant; it was capable of demolishing an AT-ST with just seven or eight rounds. A single shot was sufficient to incapacitate a stormtrooper wearing complete combat armor. Furthermore, it stood out as one of the limited weapons, alongside the lightsaber, that possessed the ability to slay a fully grown Kell dragon.
