Human may be able to be precise, but sometimes willingly choose cruelty

Alien Ensign: "Sir. The Enemy Fleet is now in Range. We are still undetected. In fact, their Sensors has just passed over without detecting us. We have clear Firing Arcs on their Flagship. Clearance for Decapitation Strike?"

Human Captain: "Denied! All Fleet. Wait for them to pass Point Alpha, then open fire with the "Spacers" on everyone except their Flagship. I want their "God King" to see what happens when you burn down a Civilian World. If anyone even so much as scratches the Paint on that thing consider your leave for the next 5 years forfeit!"

AN: "Spacers" are Rounds designed to vent Compartments, usually from Freighters and Debris so Salvage can get to it without putting themselves at risk. They pierce through the Hull until halfway through, clamp down and open ports on either end to Vent any Atmosphere. They specifically DO NOT explode or cause any harm to the Ship itself beyond the initial impact, as well as vent slowly enough to not cause harm to anything inside (or for the Crew to know whats coming). The opening venting ports are also grated and small enough to prevent Debris and valuables (or Crew) from geting sucked into space.
Obligatory: No, they are not banned yet, because nobody has ever used them in a Military setting.
