Your source literally says they’re two different words, high angle fire (which is what I said) is the correct one. Howitzer is never said. Just because they share kanji due to being similar in nature (you know, ANGLES) does not mean the exact same word is being used or implied.
"Current U.S. military doctrine defines howitzers as any cannon artillery capable of both high-angle (45° to 90° elevation) and low-angle (0° to 45° elevation) fire; guns are defined as being only capable of low-angle fire (0° to 45° elevation), and mortars are defined as being only capable of high-angle fire (45° to 90)."
In case you missed it, the term howitzer and high-angle fire are literally considered the same definition by the United States military. High-angle fire is just a term used to describe howitzers and their elevation levels. Like, I don't get it. The wording between these words is so similar that they practically share some of the same kanji, and best of all, the United States military defines the term howitzer as something
capable of high-angle fire.
I'm seriously convinced that you haven't even bothered reading my argument all the way.
Midoriya is bringing up high angle fire due to the fact that is Nagant’s whole thing; angling her shots. What happens when you shoot a bullet up? It comes down, at an angle. The different is Nagant’s bullets still hit like a truck.
Ah, yes! As if Deku himself would magically know which angle these bullets were fired at! Why did I not consider such a possibility before???
Just because the gun is angled a certain way, doesn't mean it should be classified as high-angle fire. Any bullet can be fired from a certain angle and decrease in elevation. The difference between that and high-angle fire is that the military only uses the term officially as a way to describe howitzers. A type of artillery shell. You don't see the term high-angle fire used for just any type of bullet out there.
This still does not mean he’s moving at that speed at all times, especially when he’s casually retrieving his broken phone and hanging in place. Again, he spends 4 panels in the exact same spot on the same side of a building. Deku is apparently comparable to Nagant’s bullets yet he can’t even cross around 15m in the time it took for Nagant’s shot to cross 2km, assuming Deku is actually putting effort into his speed there like you’re assuming he is. Doesn’t seem consistent.
If Deku wanted to, he could travel measly several meters in a literal millisecond if he wanted. Why would he struggle to maintain a supersonic speed just by attempting to pick up a broken phone from a few meters away? A supersonic character could easily cover that distance in milliseconds. Once again, this is a person who could flick his finger and he would create shock waves.
Do you honestly think that someone like that would struggle to maintain such a speed?
I ask of you, why would Deku struggle with maintaining a speed that he'd be capable of casually maintaining even on a bad day? It makes no sense for a guy who can sprint kilometers in seconds to suddenly struggle with moving at supersonic speeds.
What reason do you have that proves that Deku wouldn't be consistently moving at supersonic speeds in a situation where getting from point A to point B is his top priority?
”especially when characters who are much slower than him to the point that he could blitz him, can break the sound barrier in an instant” Citation needed lmao.
Gran Torino is explicitly shown to generate Mach cones, and Deku would be capable of outspending him in every sense of the word fairly easily.
Iida is also capable of generating vapor cones and traveling faster than sound.
Even ******* 5% Deku is capable of traveling over a dozen and a half meters in a fraction of a second.
The fact that Deku when using 45% of his power is blatantly faster than any past incarnation of his power (excluding 100%) along with being capable of outspending Gran Torino in every sense of the word fairly easily while also being implied to be in a completely different league of speed compared to Iida is just laughable at this point.
Do I have to explain this to you with 50 pages worth of context to get you to understand this?
This is common sense...
