It's not consistent in the books; also, bullets are the biggest PIS in fiction. Not to mention, even characters weaker than Spartan-IIs have survived shotguns and other
9-B weapons in the books. Now Assault Rifles had killed shieldless Brute Chieftains in the books, but even Mark IV Spartans are typically treated as immune to Magnums and Assault Rifles unless said bullet hit the visor. It's just a trope in fiction for everybody that isn't made of metal or doesn't wear armor to have bullets and sharp weapons be their kryptonite. But we don't do that here.
Also, no one said weapons and vehicles can't scale from characters, but the fact is fodder weapons and vehicles can't scale from top tier characters. Bullets in Halo are literally just bullets, same goes for a lot of FPS franchises like CoD, Battlefield, Wolfenstein, Gears of War, Duke Nukem, ect. They aren't spiritual, demonic energy, magic, ect enhanced, nor are they made of super fictional alloys or amped up by Toon physics, they're just lead bullets. Lead handguns are
9-C, Shotguns and Rifles are Tier 9. Same with tanks; they're just ceramic titanium tanks powered by propane gas, no supernatural or over the top elements. Stronger than their real world counterparts yes due to their statements and/or feats, but not because reverse power scaling.
Also, we actually don't usually scale weapons to each other or from their characters and wielders. If you're talking about The Master Sword from Zelda or the Falchion from Fire Emblem, those are actually special cases. They're legendary holy weapons with Divine Power. For conventional Sci-Fi weapons like Star Wars, we actually
don't scale them from the character that use them. Blasters are Tier 9, and Tie Fighters
Town level+ with only
Large Building level durability; their durability comes from being made of a fictional metal called Durasteel, not from surviving lightsaber strikes. None of the blasters or conventional aircraft or blasters are
Large Town level, or better yet
Planet level via scaling from Jedi Masters. Star Wars also has things such as using force amplification to enhance the power of their lasers, which those same lasers are way weaker naturally. In fact, looks at
Lightsaber profile; it's only
9-C. Though to be fair, melee weapons in general should just have variable tiers as their actual AP is dependant on their wielder. Additionally, the bombs from Zelda have consistently been shown to harm various
High 6-C to
High 5-A characters, but are only
High 7-A based on their own calc.
Now back to the Shotguns, they may severally damage ODST's but they're weaker than even Teenage suitless Spartans. And actual Spartans are typically unfazed by Shotguns. Their gameplay damage ratings are far different then the actual scientifically accurate energy output. Rocket Launchers on the other hand are for more dangerous to Spartans, but not shotguns. And same with the vehicles, you don't scale durability to something that oneshots you; that's the definition of reverse power scaling.
And yeah, as Xing mentioned, my RPG and Fuel Rod cannon calcs are somewhat over calc'd. It shouldn't be assume the every single cubic centimeter is fragmentized in two shots, just how much damage a tank with Scorpion's properties would normally be damaged to the point where a tank doesn't function anymore. And Fuel Rod isn't as overcalc'd but it's using the wrong assumptions for Holly's armor. She wasn't wearing MJOLNIR and was only wearing SPI Armor, which is way lighter and weaker than MJOLNIR. That being said, the calc's would both still be well into
9-A, but I'll recalc those when I have time and good resources.
