It may be necessary to eliminate a sentry in order to penetrate the enemy camp. The principle
of Nyudaki No Jitsu is used to take advantage of the psychological weakness of a sentry.
Nyudaki is translated from the Japanese to mean "idleness" or a "dislike for being industrious."
It is advisable to select your target carefully. Bear three things in mind when seeking to discover
the shortcomings of an enemy: first, never look down on the enemy and underestimate
him; second, never fear the enemy and act without confidence; and third, never hesitate..
In attacking a sentry, two facets should be considered: He must be killed as quickly as possible,
and he must make no outcry. It is preferable to remove a sentry when he will be least
missed, such as shortly after post checks that occur at regular intervals.
People sleep most deeply between 3:00 and 5:00 A.M. The body is accustomed to this cycle.
Therefore, a sentry, nearing the end of the watch, shortly after a post check, and just before
dawn, is a prime target. He probably will not be missed until the changing of the guard. Also,
those inside the camp will be in their deepest sleep and thus are less likely to hear a muffled
It should be noted that these techniques have been taught to British Commandoes, U.S. Special
Forces, and before them to Thuggees, assassins and Chinese bandits throughout history.
Have no doubt of their effectiveness and study the anatomy of the human body to know where
to place the blade accurately.
Classical Ninjitsu teaches that there are three basic methods of attacking a Sentry from ambush,
from above, below, or behind. The initial attack must be totally incapacitating and catch
the enemy completely off guard. Attacking from a position of concealment or ambush increases
the probability of success by a factor of four and increases the damage done by the attack by a
factor of three because the enemy is unprepared for the strike.
Discussed next are the five assassination options open to the knife-wielding Ninja: Slitting
the Throat; Kidney Thrust,- Subclavian Artery Thrust; Jugular Thrust; and the Heart Thrust.
Fig. 59 -Approach to within three or four feet of
the enemy and assume the illustrated stance. This
will enable you to make a lightning strike by
springing on him. The dagger is held in the lead
hand (Mu-Te) while the left arm acts to seize and
hold the enemy for the knife thrust (Soe-Te).
The stance should be a slight crouch. This will
lower the center of gravity, increasing the balance,
place the body below normal eye-level, making it
harder to see, and make it possible to approach the
Sentry silently, using the Pa Pu Step, to within
striking distance. The Chinese army teaches its soldiers to crawl within twenty feet of the enemy before standing to make the final assault. This is so
that if the enemy should suspect your presence and
turn quickly, you can make a quick rush at him over
the remaining distance and strike before he can
raise an alarm or get off a shot.
