4 Ways to Stop an Opponent
1) Loss of blood Pressure
a. Damage the heart is the quickest, most certain way but can still take several seconds, particularly if the blood is well oxygenated and the opponent is in adrenalin dump.
b. Cut or sever major arteries and veins. May take longer depending on the size of the artery, if the artery is severed or “merely nicked,” if direct pressure is applied, or if muscle constriction reduces blood loss.
c. Cut or sever minor arteries or veins such as the inner wrist. This may take the longest to cause loss of consciousness.
d. Internal bleeding due to damage to internal organs. This could be very quick or could be very slow but has few visual cues.
e. Thrust for organs
i. Military autopsies tend to support that injuries to internal organs (due to thrusts) are, generally speaking, more certain to damage and more incapacitating or fatal
ii. Thrusts must be deep enough to reach the organ. A too short knife or incomplete thrust may not reach the organ.
f. Cuts for arteries and veins
i. Tend to be near the surface and therefore more accessible.
ii. Skin can be surprisingly resilient and elastic or may “move” during your cut.
g. At least one strike can cause loss of blood pressure: to the neck. This is the classic “Judo Chop” and over-stimulates the vagus nerve which regulates blood pressure.
2) Central Nervous System (CNS) damage
a. A thrust to the brain or chops to the spine can shut down an opponent instantly
b. These are highly sensitive organs and are protected by bone which may be difficult to penetrate
c. These are also, comparatively speaking, small and hard to hit, particularly when an opponent is resisting or even just “moving.”
d. The CNS may be temporarily “disrupted” by blunt force trauma.
3) Structural Damage
a. Broken bones may cause incapacitation of the limb.
i. Incapacitation of a leg may cause
1. Reduced mobility
2. Complete immobility
3. Opponent collapse (falls to the ground)
ii. Incapacitation of an arm may cause
1. Inability to hold a weapon
2. Inability to grapple
3. Inability to strike
b. Damaged joints – similar effects to that of broken bones
c. Severed tendons, ligaments, or muscles – similar effects to that of broken bones
d. Collapsed lung or obstructed breathing
i. May cause reduced aerobic ability
ii. Loss of consciousness
e. Crushed muscle
i. May cause similar effects to that of broken bones
ii. Less reliable, more difficult to achieve, and more difficult to gauge success or extent of injuries
4) Psychological Effects
a. Impressive or intimidating presentation from you
i. Intimidating flourishes (moulinets, navaja flourish, sinawali, etc.)
ii. Loss of an ally or co-opponent
iii. Fierce, determined, angry, or otherwise disconcerting presentation from you
c. Sight of own blood
d. Belief that being injured (stabbed or shot) means that he must fall to the ground and “die.” (i.e.: psychosomatic)
e. These effects are not dependable
i. There are lots of stories about people who didn’t know they were stabbed or shot until after the fight when they say their own blood.
