Call for suggestions and opinions on renaming

Since everyone has been saying my book title is too idiotic, and having a title that is too long is also unfriendly for upcoming promotional features, I am hereby holding a call for title change suggestions.

(Sigh, it's not really that I insisted on picking such a goofy title, but I honestly couldn't think of anything else.)

I currently have a few alternative options, which I racked my brains until my grey matter was squeezed dry to come up with:

"Apocalypse Heavy Armor": Heavy-armored savage beating of little monsters
"Beneath the Iron Rain": After the iron rain passes, the wasteland embraces a new birth.
"Monsters, Gunpowder, and Steel"
"Armor-Piercing Shells Do Not Believe in Carbon-Based Monsters"
.........

I really can't think of any more. Let's put it to a vote.

"Monsters Running Rampant, But I Am the Regular Army" is currently holding a call for title change suggestions and feedback, currently being typed out, please wait a moment.
