At the low end, it can be as simple as a bullet hitting a nonmoving target, and at the high end, it can include the immense energies of a collision between an incoming ballistic missile and an intercept vehicle. It is a subset of kinetic kill, which includes explosives and other physically destructive "hard kill" mechanisms.
