Mental force vs. physical force

In Terran warfare, mental force and physical force are the major forces of military and interpersonal combat. They are inherently different from each other.
==Physical force==
Physical force was the primary force of combat before the founding of Terra. Persons and armies would attack each other's bodies instead of attacking them directly. 
==Mental force==
In Terra, persons and armies use mental force against their opponents. They attack their enemies directly by attacking their minds, deceiving them, emotionally manipulating them.
==Mental force vs. physical force==
Mental force is considered more powerful and damaging than physical force because a person's mind is their centre of thought, planning, and decision-making. Damaging the mind severely damages the person.
