"Commentary For Chapter 4"

Chapter 4 of Michaelson's  "Sun Tzu's For Execution" is entitled "Disposition of Military Strength", and it's about what give certainty in a victory. That does not come through fierce fighting, but making no mistakes in it. He point's out three things for this to happen. They are be invincible, win without fighting, and use information to focus resources.

Be Invincible
This is a skill a warrior would master to be successful out in the battlefield, because this gives them the ability to protect themselves while gaining a complete victory. Invincibility is being in a defense position, and waits for an opponent to be vulnerable that will open itself for attack. Vulnerability shows an opponents when it is inadequate, and skill attackers will take advantage of this to be on route to victory.

Skilled warriors do not attack an enemy's strength, but studies them to where they know when they will be exposed. Being invincible is able to blend oneself with the earth, and this creates vulnerability for opponents. They get nervous when they cannot see who they are attacking, and could believe they are out of position. They may do something that causes them to instead be in position it causes them to be out of position, than the skill warrior attacks flashes like it is coming down from the sky.  That is being invincible, and that will bring victory.

Win Without Fighting
People believe that a successful warrior comes from victory in fierce fighting, but Sun Tzu does not define that as the excellence of victory. To him the excellence of victory is winning battles without making mistakes, and that's conquering an enemy that's already defeated. Not firing a single arrow for victory is more impressive than victory through fierce fighting, becauses its quick, does not exert a whole lot of energy, and saves resources. Learning the value of information is where victory without fighting begins.

Use Information to Focus Resources
To get useful information a warrior must study the elements of war. The elements of war are the measurement of space, the estimation of quantities, the calculation of figures, comparisions of strength, and chances of victory.
Studying these elements will give warriors information it needs to determine if it is more valuable for them to be invincible, or flash attack its enemies. This will also give an idea of how much space is require for it to move its operations, and how much supplies they need. This is value information that can give warriors the calculations to forecast victory.
