User blog:The Awesome X!/Why don't the monsters use mortal weapons?

This is similar to the never-ending question of why demigods don't use mortal weapons like guns to kill monsters. It was demonstrated by Mr. Chase in The Titan's Curse when he sprayed the monsters with Celestial Bronze bullets from his Sopwith Camel. The only explanation I can come up with is that it's too costly to do that cause C. Bronze is rare.

But demigods can be hurt or killed by both mortal and..."godly"? weapons. So a bullet, or a rocket launcher, or a bomb, or a C. Bronze sword, or even a killer dolphin can injure or kill them. Apparentely that's why demigods are so special; they can interact with both the mortal and immortal world.

But if the monsters want to kill the demigods, why don't they use mortal weapons? Kronos could have realized that a majority of the Camp was in Manhattan and fly over with a plane or something and drop a bomb. BOOM. No more demigods, and none of his troops are injured cause they can't by mortal weapons.

Or if he doesn't want to wipe out a city, equip his troops with modern weapons, like automatic rifles and rocket launchers and sniper rifles and stuff. I'm pretty sure a sniper rifle would be a lot more effective than a bow and arrow.

And why don't the demigods and monsters alike run in with like Kevlar suits and stuff? If a bullet can't pass a Kevlar suit, then an arrow sure ain't gonna either. Even a blade would have a difficult time passing through.

Yes, it would take away from the whole atmosphere of the series and it wouldn't be as much mythology as it is just people gunning each other down, but can someone please offer an answer as to why the monsters are using ancient weapons when they could much easily destroy demigods using modern, mortal weapons? This is a lot like the Harry Potter question of why didn't Voldemort just bomb Hogwarts or something. Or take out a few shotguns and BAM no more Chosen One.
