Disclamer: use of AI for this project
Cannons: louder, reverb, realistic boom (increased range of audio)
Autocannon bullets: the "whizz-by" of the bullets have realistic sounds instead of the rubber band sounds
Shell explosions (Flak, HE, etc...) : louder, reverb, realistic boom (increased range of audio)
Shell "whistle": realistic strikes sounds and whistling of shells raining down (increased range of audio)
Mortar: Cannon changes but w/ a cool signature ringing sound
I recommend pairing this with Sound Physics Remastered.
You could try this with other MC versions besides 1.21.1, idk if they work.
