Subjugation requirements for monster classes (Conventional weapons):
D-class: Cold weapons can be used although not recommended. Small caliber firepower is recommended for use with most monsters in the D-class category.
C-class: Monsters of this category can deflect small caliber bullets, intermediate caliber and higher is recommended for subjugation of such monsters.
B-class: Armor piercing bullets and above can damage such monsters, although up close combat is not recommended. Usage of artillery is the most valid strategy against most monsters of the B-class category.
A-class: Artillery and missiles are the only thing that can damage the monsters of the A-class category. DO NOT ENGAGE IN UP CLOSE COMBAT.
S-class: No valid strategy has been created to subjugate monsters of the S-class category. The only successful subjugation case of an S-class monster was the subjugation of the world tortoise where a nuclear warhead was dropped, devastating the area, making it inhabitable.
[The world tortoise was a non-agressive monster although because of its huge size, it created an ecosystem where a lot of dangerous monsters lived. Making it a target for subjugation.]
