I think we may have to come around the idea that Japan just won’t get a 1:1 replacement for the Ho-Ris that fit the same exact role and function. We could certainly find vehicles that would fit at the current BRs, such as the four-barreled Type 60 SPRG prototype, or at a slightly lower BR, the various light wheeled vehicles fielded by both Japan and Thailand that used recoilless rifles, possibly a pre-production Type 99, or maybe even the Ho-Ri II (but finding information on certain aspects is difficult/non-existent).
The details of the Ho-Ri II are known down to the internals. That’s why we know that it would never be positioned in the 6.0-7.0 bracket, or even the 6.0-7.0 bracket. While it uses the same gun, the armor would be far worse than either the Ho-Ri Prototype or the Production. Instead of the 75 mm or 125 mm sloped hull, it would have the same flat 75 mm hull that the Chi-Ri has. Instead of the 150 mm or 225 mm casemate, it would be stuck with a 125 mm casemate. The only thing it has over them is the twin 20 mm on the rear of the tank, the slightly better mobility over the Prototype, and the stereoscopic rangefinder it has in its cupola. So, it would have better long-range performance due to the rangefinder, but its far worse armor would make it hard to sell as even a 6.3 tank where the Ho-Ri Prototype sits, and it’s not even a question is if it could replace the Ho-Ri Production – it can’t.
Sadly, neither Japan nor Thailand have a good 1:1 or 1:2 replacement for it. Even the hypothetical inclusion of a South Korean or SEA subtree wouldn’t provide a replacement. This is mostly down to the Ho-Ri Production being fiction and heavily armored tank destroyers, which the vehicle effectively despite it being fake, being rare and really only developed by the Big Three+France. Though, there are a number of vehicles that could be added in order to make the Ho-Ri Production superfluous, including:
- Japan
- Type 19 HSP
- M270
- Type 73 truck with:
- Type 64 MAT
- Type 64 (B) MAT
- Type 64 (C) MAT
- Type 60 APC with:
- Type 64 (B) MAT
- Type 64 (C) MAT
- Prototype w/ four launchers
- SS-4 w/ Type 64 MAT
- M24 w/ Type 64 MAT
- Thailand
- M113 APC w/ TAT-251
- V-150 w/ 90 mm Cockerill
- BTR-3E w/ 90LP
- M41A3 w/ MK4A1
- M966 truck w/ TOW
- M113A2 APC w/ TOW
- M37 truck w/ 20 mm M39A2
- Truck w/ 20 mm M61A1 Vulcan
- M163
In short, all Japan has left to provide that BR range is basically just crappy ATGM spam, in multiple flavors of either tracked APC or SPRG prototype, or slightly faster wheeled truck. The M24 retains its gun and would be different. The M270 would be a slightly more powerful Type 75 MSSR, while the Type 19 HSP might be in the 6.0-7.0 range due it being truck. Thailand would be the ones to provide any more variety to the range, with an assortment of Cockerill tanks (V-150, BTR-3E, M41A3), TOW carriers (M966, M113A2), 20 mm AA guns (M37, M61A1, M163), and the odd M113 with a 25 mm.
The removal of the Ho-Ri Production will come down to whenever Gaijin “feels like” the BR range wouldn’t be ruined by its removal.
