15/7/18 [1.79.1.136] Ki-67-I side gun arc issue

1. The full name of the vehicle affected. 

  • Ki-67-I Ko
  • Ki-67-I Otsu


2. A detailed description of the issue you have or what you see as being erroneous regarding its representation in-game.

There is an issue on the field of fire of Ki-67 side gun.

There are different values depending on Source, but historically there was at least field of fire wider than in game.

 

 

From the TAIC Manual of May 1945:

  • Gun elevation: +40°
  • Gun depression: -75°
  • Gun traverse range: -75° / +30°

 

In game:

  • Gun elevation: +25°
  • Gun depression -20°
  • Gun traverse range: -30° / -12°


3. Unless the data is taken from an official Gaijin statement, please provide a documented test and provide the Client Log from that session.

I checked the side gun field of fire with test flight and custom battle.

4. A detailed description of the fix you suggest. Provide sources including reference that underline your position. This is up to the discretion of the Technical Moderator handling the report, however the number of sources required depends on the type of source presented: 

Since I could not find detailed field of fire value data in the OEM Manual, I will suggest that you adopt data from the Allied Forces historical report document and reflect it in the game.
