Where did you get your information on offense vs defense? It bears no relation to anything I've ever read or had training in, and has the complete opposite recommendations.

What makes you think that offense seeks to destroy, or that defensive seeks to disable? If anything, defense needs more power, not less. The key difference is that the attacker can choose the time and place of the attack, and so can either find a time and place that works with whatever amount of power they have available (note the tendency for mass shootings to only happen in "gun free zones"), or call off the attack. Defenders do not know when they will be attacked, and so they need as much power as possible to compensate for possibly being outnumbered or caught in a disadvantageous place. That's why defenders need bigger magazines and more effective ammunition.

But both ultimately seek to control, not to destroy or disable. Once you have control, destruction is easy. And if the opponent has a firearm too, then there isn't much practical difference between disable and kill.
