I’d say AMX-40 should definitely get a reload speed buff for the simple fact that the Leopard 2K is objectively much superior due to the vastly better turret rotation and elevation speeds, which are far more important than thermals.

If you can, try to drive the XM800T and HSTV-L or Leopard 1 (specifically the original Leo 1).
Despite the XM800T and HSVT-L weighing very little, having over 30 HP/tonne, their low speed turning is very sluggish, it feels like you have input lag when trying to turn with them. Leopard 1 is similar as well, to the point that the heavier A1A1 turns faster.
The AMX-50 Surbaisse is also a noticeably more mobile and responsive than the M103, despite being a tonne heavier and having only a slight HP/tonne advantage (0.42)
Are there any sources showing that the AMX-30 S DCA did or did not have APDS?
Probably going to come next major update or a later “It’s Fixed” (I’d guess next major update, since it’s in about a month). I’ve heard of some other somewhat significant buff coming for French vehicles, including a buff to how elevation of coaxial 20mm for French vehicles is handled (all AMX 30 and AMX32, AMX 40 except for the 8.0 premium), so that the coax doesn’t overshoot, as well as yet another buff to the accuracy of the 30mm of the tiger, that should be fixed but not implemented.

I shared this French article in the Valiant thread. I don’t understand French but it does cover AMX-32 and might provide assistance.

Somebody start the timer.
Has anyone reported the incorrect engine sound for both AMX-32s?

My report about the AMX-40’s missing composite armor in the turret has been accepted.

So there is no way to buff the optic magnification?10x immutable gunner sight is hard to use…
Gunner sights on these vehicles are terrible, surely they aren’t accurate.
@Mulatu_Astatke @LeGrandSarrazin @vizender
The fixed 10x optics is really awful.
We needs a low magnification for wide FoV detection such as 4x-10x or 3x-10x.
I doubt the thermal channels on AMX32120 and AMX 40 may have that low magnification.
I believe that even if they were able to find sourcing that directly states the optics aren’t fixed at 10X, I doubt Gaijin would act to implement it.
There’s many glaring innacuries that have been pointed out by this thread like AMX-32 (105) not having thermals or AMX-40 missing turret composite that have been “accepted” yet have 100% never crossed the eyesight of any dev.
I don’t remember what magnification the 10x is based on, but I remember looking at all the different magnification, Optical and thermal, but only 10x was mentioned. Until someone finds a source mentioning different magnification, thermal or optical, we are stuck with this sadly

The x10 is the daylight magnification of the M581 gunner’s telescopic primary sight, not the magnifications of its Castor thermal camera.
The optical characteristics of tank sights are actually like binoculars, and its magnification can be defined by the ratio of the focal length of objective lens to the focal length of eyepiece lens, or the ratio of the effective objective lens diameter to the exit pupil diameter.
M=f_objective/f_eyepiece =D/d
But most parameters such as the focal length or lens diameter of military AFV sights are confidential. Therefore, we can use the original definition of magnification, that is, how large or small a object can be reproduced on the image plane (the degree to which the object being viewed is enlarged) to calculate an approximate value.
The dimension of the object that a sight can observe generally depends on how wide the field of view is. The field of view is inversely proportional to magnification, that is, lower magnification expands it and higher magnification narrows it.
For example, at a specific observation distance, the image dimension observed at a high magnification M_h is M_l/M_h times the image size at a low magnification M_l.
In order to calculate a specific magnification, it can be simplified to the following formula
M_(low for WFoV)=D_(image dimension for NFoV)/D_(image dimension for WFoV) ×M_(high for NFoV)
The Castor thermal camera used by the AMX-40 is a dual field-of-view thermal imager. The following diagram is a typical step-zoom dual-field optical system, which uses different lens arrangements to change the focal length to provide different magnifications (rather than continuous zoom).
Thomson-TRT has designed three lens configurations for Castor for different applications, and the Castor/DIVT-16 system used by AMX-40/AMX-30B2 Brenus is variant 1.
Spoiler
The Castor thermal camera provides x2 electronic zoom. Other sources indicate that the DIVT-16 has a maximum magnification of x20, so the optical high magnification of the Castor is x10.
Spoiler
The approximate value of low magnification can be solved as follows:
Now if assume the object distance = 100 meters, then the given horizontal field in narrow FoV is 71 mils (NATO) and the given horizontal field in wide FoV is 160 mils (NATO).
We may choose base of isosceles triangle formula
(2∙h)/tan((180-β)∙0.5∙π/180)
Thus the horizontal image dimension in NFoV and in WFoV, respectively, which are
D_(horizontal for NFoV)=(2∙100)/tan((180-(71∙360/6400))∙0.5∙π/180)
and
D_(horizontal for WFoV)=(2∙100)/tan((180-(160∙360/6400))∙0.5∙π/180)
Then we use the given NFoV magnification x10 and the magnification rate formula derived above to get
M_(horizontal for WFoV)=10∙D_(horizontal for NFoV)/D_(horizontal for WFoV) =4.4301658696
So here we solve the magnification rate in WFoV, obtaining
M_(low for WFoV)=4.4
Note that this magnification value is an approximation. To verify the accuracy of this formula, we substitute the parameters of other sights to check the error.
AN/VSG-2 TTS, given x8 magnification and NFOV, solve for the lower magnification under WFOV
AN/VSG-X TIS, given x9.8 magnification and NFOV, solve for the lower magnification under WFOV
PERI-ZL, given x10 magnification and NFOV, solve for the lower magnification under WFOV
OIP Mk-2 FCS, given x12 magnification and NFOV, solve for the lower magnification under WFOV
The error is between ±0.5, and the error will increase if the given magnification or field of view is approximate. If one magnification is known, the formula can still calculate the approximate value of the other magnification.

Wow that’s very interesting. I knew some very basics about optics but you reached me quite a lot of things. Sadly since this is only approximation I am not sure we could make a report on that. Thoughts @WaretaGarasu ?
Do we have any info about Castor thermal camera‘s FoV data？I remember Gaijin accept magnification approximate value by calculating the formula with FoV
I wish these got their psuedo-stabilizers
You mean the FCS that can decide to shoot when the gun is aligned with the firing position even when moving ?
Yeah, that’d need FCS to be implemented sadly
