Type 24 rifle with type 28 grande launcher [Valkay´s BP guns]

427A0C5E-4329-4CB2-8AAC-D7FE18BA47E9

Hello bajtársak and fellow forumdwellers,
I’m starting a new series focused on suggesting guns for the Battle Pass specifically, because we get a new BP gun every 35 days and the developers put unusually high effort and care into them, while only 3 guns were added to the Tech Tree in the past 7 months.
Since Battle Pass guns are limited in their numbers, I will naturally not suggest anything that should be in tech tree, however this limitedness does make them optimal for testing a new mechanic or adding a gun that had many different unique variants; some of which could be added later as premium, event or to the tech tree. The Type 24 with GL that I will demonstrate in the topic has both new mechanic and reusability potential.


The Type 24 rifle

The Type 24 rifle, also known as the Chiang Kai-shek rifle which is how its most commonly referred to by western gun enthusiasts or Type 79 rifle by the Communists, however I will simply call it Type 24 from now on for simplicity’s sake.
The Type 24 was a licensed clone of the Mauser standard-modell, which was designed in the Weimar republic in 1924 (only entering mass-production in 1933) and could be considered the big brother of the Karabiner 98 Kurz.
The National Revolutionary Army of the Chinese Republic purchased the license for the Mauser standard-modell in hopes of standardizing its rifles.
It was one of the most common rifles used during the Second Sino-Japanese War, with the Type 24 being the standard issue service rifle of the National Revolutionary Army, but captured Type 24 rifles were frequently issued to puppet troops under Japanese command and saw use with Japanese and Communist Chinese soldiers too.

One must be careful when adding a Type 24 rifle to a WW2 game, because they were produced until 1949, not to mention that there were slight differences between arsenals that produced them.
Naturally, the Type 24 rifle could be reused with the grenade launcher attachment replaced by a HY1935 bayonet.

The Type 28 grenade launcher was designed by Yury Romanovich Larikov, a Russian weapon designer in 1939.
It could be attached on both the Type 24 rifle and the Hanyang 88 rifle.
In order to fire the grenade, a special purpose cartridge must be loaded in the rifle, however the attachment does not need to be removed from the rifle in order to fire it normally.


In-game:
The Type 24 with Type 28 grenade launcher’s most unique aspect is it fires time fused grenades that does not explode on impact, instead the grenade explodes 7s seconds after its fired from the rifle. It cannot be cocked or tempered to explode earlier.
The Type 28 grenade is ineffective at close ranges since it can be thrown back by the enemy.
The time fuse makes it more situational than impact grenades and require more experience from the player’s side too. Making the Type 28 grenade the most effective at medium range engagements in open terrain or in across-the-streets fire fights inside cities, firing the grenade into a building through an opening.

By design, the usage of the time fused Type 28 grenade launcher is supposed to be more difficult than other in-game grenade launchers that fire impact grenades. The trade off is that the Type 28 grenade is about as powerful as a hand grenade and that the rifle should be BR2.

The Type 28 grenade launcher is a permanent attachment on the rifle and does not need removing animation either since the rifle can be used with that on it anyway so there is no reason to remove it what-so-ever.


However in order to fire a grenade from the rifle:

  1. A Type 28 grenade must be loaded in the front
    1.5: If the magazine is full, the shooter must remove one bullet from the magazine, this step is skipped if there are 4 or less ammunition in the magazine.
  2. A special propellant cartridge must be loaded
  3. The grenade is ready to be fired

During World War II, the norm for rifle grenades were time fused projectiles, however we only have anti-tank and anti-infantry impact grenades, not to mention that all function as the Mosin Diakonov should (does not need special propellent charge), but that should be the unique exception.
The Type 24 would test the feasibility of more common and authentic time fused rifle grenades in the game.

technical documents

Details about attaching the grenade launcher to the rifle, ability to use the type 28 grenade as a hand grenade (similar to German rifle grenades) and instructed carry, firing positions.
Details interesting for researchers and enthusiasts but for people that are not on a spectrum, its a tad bit boring.

I have objection against it:
  • being available to Japan
  • being in the Battle Pass
  • being BR2

Thank you for your time and attention!

I hadn’t really thought about it before, but in that case, the Japanese Type 100 grenade launcher, which fires standard hand grenades, shares the same feature. And if that’s the case, it would be easier to just fix the error for the existing launcher.

What’s the point of a rifle with an under-barrel grenade launcher when Japan already has the exact same thing in the progression tree?

The Allies desired a similar weapon in response to the appearance of the Japanese “Mortar.” Here is the British equivalent.
The image shows the Blanch-Chevalier grenade launcher, developed during World War I and manufactured by J. Blanch & Son. The design consists of a Martini-Henry rifle modified to mount a 2.5-inch caliber barrel intended for firing grenades. A .577/450 blank cartridge was used to fire the weapon (after first removing the safety pin). To date, only one surviving example of this weapon is known to exist; it is held in the Royal Armouries collection.
Grenade weight: Each specialized grenade weighed approximately 600–700 grams. In terms of mass and explosive content, it was comparable to the standard British Mills Bomb No. 5/No. 36 (which weighed about 760 grams).

They don’t have the exact same thing in the TT. Even ignoring the fact that the Type 24 rifle isn’t in the game at all, there are no non-impact rifle grenade launchers in the game. This suggest both a new weapon and a new type of rifle grenade launcher.

Impact grenade launching rifle in TT vs time fused grenade launching rifle that works differently too and is on different BR too.
There is a point, or would you prefer over powered stuff?

I think you did not read the suggestion and you got things wrong.

In theory, it was possible to adapt the American 60mm mortar round to the caliber of the Blanch-Chevallier weapon (63.5 mm). Crucially, this did not require physically enlarging the mortar body itself—whether by filing it down or by adding metal. The Blanch-Chevallier grenade launcher (developed in 1916 based on a Martini-Henry rifle with a heavy 2.5-inch barrel) was essentially a smoothbore tube that fired using the energy of a blank cartridge. To launch a standard 60mm round (such as the American M49A2) from it, one problem had to be solved: the 3.5-millimeter difference in diameter, which would allow propellant gases to simply whistle past the round without propelling it forward. At the time, there were two theoretical approaches to solving this issue.
Method 1: Using an obturating ring (the simplest approach). To ensure a 60mm-caliber mortar round traveled snugly through a 63.5mm barrel, one simply had to fit an expansion ring—acting as a wad or sabot—onto its body. How it was done: A ring with an inner diameter of 60mm and an outer diameter of 63.5mm was machined from soft metal (copper, lead), dense felt, leather, or even wood. How it worked: The ring was placed over the cylindrical section of the mortar round. Upon firing a .577/450 blank cartridge, the gases exerted pressure on the ring. It would expand, completely sealing the gap in the barrel (ensuring obturation) and propelling the 60mm round forward.
Method 2: Using a rod extension (the rifle grenade principle). The original Blanch-Chevallier was designed for specialized grenades. However, it could be adapted to launch a 60mm mortar round as a “super-caliber” munition—meaning it did not need to be inserted into the barrel itself. How it was done: A sturdy wooden or metal rod was used, with a diameter slightly less than 63.5 mm (so it would fit snugly into the Blanch-Chevallier’s barrel). How it worked: The rod was inserted into the weapon’s barrel, and its protruding end was securely attached to the tail section of the 60mm mortar round (replacing the standard stabilizer cartridge or fitting directly into the tail tube). Upon firing, the propellant gases propelled the rod forward, carrying the mortar round along with it. Many World War I-era rifle grenades operated on this same principle.

And why do you think that a 7s delay is feasible? especially with the heavily nerfed rifle grenades we have?

People would use it and realize how much of a stupid gimmick it is… only to never be used again.

So after you shoot it… explodes in 7 seconds… after the enemy has already passed it.

To reward skilled players? I applaud you if you think this is any bit useful in any scenario.m

Really, count out 7 seconds properly and or time it and then try to apply that to any situation in a practical game… predict the enemy? Enjoy doing no damage even if you do.

A BP gun? AbsoLUTELY not. What a waste.

And being BR2? What? So you can have a workaround for having rifle grenade in 2? Smh.

The reasoning is that it’d be in BR 2 because it’s worse than the standard GL rifles
