It is a hold over in my training from less peaceful days as a platoon sgt of a light infantry company.
"If you have the enemy on the move, don't give him time to regroup, think, or sort out his options, . . . pursue and engage".
Once I crossed over into "taking action" (which I had done in challenging and drawing), . . . pursuit and engagement were really the only options because of the layout of the house and my personal location at that moment.
Plus, . . . forcing them to move, . . . would most likely cause them also to reveal their true location by the noise they made by moving.
May God bless,
If you can breathe, . . . thank God!
If you can read, . . . thank a teacher!
If you are reading this in English, . . . thank a Veteran!
