For the most part, the offensive use of lethal force is reactive. An individual who works in compressed environments will often work initially from reactive to competitive state of interaction, as he needs to identify, see better, etc. Being able to perform out of the position you find yourself in, rather than the one you wish or plan to be at is probably the most important, neglected aspect when it comes down to the development of SOPs, as the human mind is often leaning towards anticipated success and proactivity, rather than the opposite.
Extracting angles is also a human behavior compliant method, as any individual will flinch –away- from any sudden threat or unknown that appears all the sudden, and in short distance. Same applies towards loud explosions or the sound of a gunshot. Since EA already conditioned the individual to such occurrence of “withdrawal”, all it takes for the individual is the instinctive “push”.
One of the most consist occurrence we have seen in the real world, as well as FOF scenarios, were situations of which the individual use of the angles was disrupted by the threat interaction with geometry. important training phases in our CQB courses before conducting any force on force is practicing and understanding the realistic relations of extracting angles and especially the mechanics of it. Extracting angles can be used for reaction to sudden mobile threat, stoppages, callouts, self-extract, etc.
Since EA is forced due to reaction based constellation of events, Once understood, the individual survival chances are dramatically increased, and occasionally allow the individual to turn the tide and regain proactivity.
