How effective was human weaponry during the invasions? Or even the age before it, the age of dungeons?
How effective was a standard firearm? A gun? The very weapon that had carried man to the top of the world? How effective was a rifle? How effective was a ballistic missile? How effective was a tank? And what about a jet?
A standard gun, the nine-millimeter, is capable of killing a human being, and most F-rank and E-rank monsters, save for those that are specialized in defense. The standard rifle will protect you even against formidable D-rank monsters, even those specialized in defense.
However, a C-rank monster will thwart almost all manners of 'normal' weaponry. Any gun that a normal civilian can purchase, as well as the standard rifles given to soldiers, will stop being effective at C-rank.
Why? For what reason is a C-rank monster, and an awakened, relatively safe from standard firearms? It is because their bodies are different, or rather, the quality of their mana.
