War Thunder: History of the Na-To 

I'm not completely sure what you mean by its not technically a TD since it was designed with the sole purpose of destroying the new armor being produced by the allies; it would be comparable to the 7.5 cm PaK 40 auf Raupenschlepper Ost (RSO) or the Sd.Kfz.251/22 7.5 cm PaK40 L/46 auf Mittlerer Schützenpanzerwagen (Pakwagen) that Germany used which were tank destroyers as well. As for the name, I have multiple sources both old and new that call it a Chi-So, the other names I've seen a couple of times when talking about it in a non-combat scenario is the Type 4 medium-duty tracked freight car and the Type 4 fully tracked troop carrier. It was derived from the chassis of the medium Type 4 Chi-To tank and named the Type 4 Chi-So for the armored carrier and the mortar version was the Type 4 Ha-to:)

@@MasterSquishies apologies, I meant here as in the category. Yes this is a vehicle that destroys tanks but a tank destroyer usually is a tank that's made to destroy tanks. Like the M10s or the Su-122s or Jagdpanzers. Also, I get my information from Japanese official reports, I can direct them to you later if you'd like, but they're all in Japanese.

@@MasterSquishies Also the Chi-So isn't based of the Chi-To, where did you get that? If anything its development came from the Ho-Ki, which is why I made the Sd.Kfz (half track) comparison, it's original use was troop transport, you can see that still with the layout of the back, even in the Na-To.

@@FRIEND_711 Sure, I'd love to see the reports, development documents, or shipping logs. As for the tank destroyer role, it's just any vehicle that focuses on tank-to-tank combat while any other role comes secondary; the Sd.Kfz.251/22 7.5 cm PaK40 L/46 auf Mittlerer Schützenpanzerwagen (Pakwagen) for example was a troop transport modified to house a PaK 40 for the purpose of tank destroying and indirect fire support this then change that model from a troop transport to a tank destroyer:)

@@FRIEND_711 So the first fully tracked APC was the Type 98 So-Da designed in 1937 using the Type 97 Te-Ke tankette but was introduced in 1941, next was the Type 1 Ho-Ha which was designed in 1941 based off the Sd.Kfz.251 but didn't start production until 1944 and was a half-track, following that was the Type 1 Ho-Ki which was designed in 1941 and started production in 1942 with maybe only 200 ever built, and finally the Type 4 Chi-So which started production around 1944 and used the Type 4 Chi-To chassis design which you can see very clearly in the tracks, sprockets, and wheels whereas the Type 1 Ho-Ki as a completely different design in the suspension and Type 3 Chi-Nu has more spacing between the wheels and a different track design, the only chassis left is the Type 4 Chi-To which fits perfectly with the Type 4 Chi-So:)

Lol:)

It's so good, the LG is my favorite so far for Japan though:)

Glad you enjoyed:)

Thank you and you're welcome. As for there being a newer version or not, the Na-To was a one-of-a-kind production from Japan; there wasn't really a vehicle like it produced after the war, but the Type 4 Chi-So armored personnel carrier was replaced with newer versions:)

Correction, I did some digging and I found Prototype Type 4 Heavy Mortar (Pigeon) which uses the Type 4 Chassis:)

@@MasterSquishies Thank you verry much for answering and digging in the internet for me!!

@@_McHero_ You're very welcome:)
