Questions tagged [kinetic-weapons]

For questions about kinetic weapons, their uses, technology, and application. Kinetic weapons move a mass to speeds hostile to the target. That mass may be as small as an electron or as great as an asteroid, so long as the question is about the object accelerating the mass and not the mass itself.
