Okay, I will propose the name be changed to “20 mm So-Ki Type II”. Is this more correct?
As for the elevation, considering that we do not know the specific angles of the twin So-Ki, I think it’s safe to bet that it is similar to the Ke-Ki, from which it is derived.
I launched the War Thunder client and looked at the stat card. I realized that the notation “20 mm So-Ki Type II cannon x 2” might imply a quadruple-mounted cannon, so I thought it would be better to use “20 mm Type 2 cannon x 2” instead. I apologize for the confusion.
I will provide the source of the photo and diagram showing the elevation angle of the 20 mm Type 2 Ke-Ki AA cannon, which ranges from -15° to +95°.
If you see the new comment I made, I went with “20 mm So-Ki Type II”, as this was specifically developed for usage as a dual-mount AA on the Ke-Ni. But if Gaijin insists on having the “x2” notation, we could have “20 mm Type 2 Ke-Ki x2”, or “20 mm Type 2 x2”. Latter is more suitable in terms of consistency regarding other SPAA, in my opinion.
I think the photo in the report is of the 20 mm twin-mounted So-Ki model I AA cannon.
This is the 20 mm twin-mounted Type 4 So-Ki model IV AA cannon. This pintle mount allows for quick control of elevation using the gunner’s shoulder and waist bands instead of a crank handle. It was developed to shoot down F6Fs and other aircraft that perform low-altitude strafing runs. I believe the basic performance of this cannon, such as muzzle velocity, rate of fire, and sight, is the same as the Type 98 AA cannon. This anti-aircraft gun was supposed to be mounted on the Ho-RI II.
i did some editing looking at the CTWV RCV commander camera and found out that it only have -10 and +20 instead of -20 and +30 like this old forum posted.
Websites without source list are quite unreliable. I could report it with just that document, but I’m sure someone here should have a Japanese book or two.
@tester188 do you have anything about Chi-Ha’s roof armor?
According to Japanese books, the top turret and hull armor thickness of the Type 97/47 Chi-Ha is 10 mm. However, even Japanese books can sometimes be inaccurate, so we need to check original blueprints or surviving examples in museums to be sure.
It’s only good against light vehicles/lightly armored mbts and helicopters. Unfortunately at that br you still face many heavy tanks.
It gets better when you get the apds ammo but it’s still not good. Might be better to slightly uptier it to face more lighter vehicles
