Many people in the firearms and prepper-survivalist communities like to ramble about their impressive “combat mindset” and “killer instinct.” People who have repeatedly faced violence successfully, especially those who have done so in a professional capacity, understand that guns and gear are of tertiary importance, at best. Even physical conditioning is secondary to the critical importance of cultivation and continuous development of a proper mental attitude— combat mindset.
That mindset is composed of three attributes: an unwavering but well-founded conviction in the effectiveness of your training and ability, an absolute willingness, if not anticipation, to apply that training to kill bad people, and the intestinal fortitude to overcome whatever obstacles arise in order to survive to lay hate and discontent on the enemy.
Interesting read and a must read if you are a gun owner...
