1. INCAPACITATING SHOT. Instant incapacitation is the immediate cessation of hostile action in a target and most likely causes immediate loss of life. It is the goal of any engagement but not a likely outcome with just any technique except one.
a. To achieve instant incapacitation the shot must destroy the brain, specifically the medulla oblongata. Usually there is only one chance to get an instant incapacitation shot right, so slow down and ensure that you take a good shot. For a straight-on shot, the bullet must travel through the ocular-cranial cavity or sinuses. The ocular cranial cavity is an area easily referenced by facial features. This area covers from the bottom of the nose up to the eyebrows and from the outside corner of the eyes inward and is referred to as the “T-Box” for our purposes.
b. Other areas of shot placement may result in the round skipping off the hard bone of the skull or causing only a minor, non-incapacitating wound to the face.
c. Perfect shot placement should be at the bridge of the nose. A side shot must travel through the ear area. If the target is prone or, you are firing from an elevated position, the round should strike at the hairline, angling downward, to where the spine joins the base of the skull.
d. Since the medulla oblongata is such a small target, it is essential that the shooter can apply the proper offset aim point to achieve precise shot placement.
e. Regardless of method, always follow-through back to the head afterward to insure that it was indeed an incapacitating shot.
f. Offset Aim Point is the point at which the shooter must place his sights to achieve proper shot placement. Since the rifle is BZO’d at 300 yards (or field expedient at 36 yards) and the line of sight is 2.5 inches above the bore, the round will not strike exactly on the aim point except at these ranges...
