I was taught and I train like akalinin. 2 to the thoracic cavity, 1 to the cranial ocular cavity. If there’s even a slight hint of body armor, go straight to the cranial ocular cavity.
Breachers are always gonna be Rambo’d up. Eyes, Goggles..... every time unless the pu$$ies have BA shields.
Then maybe the ankles or shin - bones.
