What !!! Diffusion Restreinte
 
The GOA is knocking to your wall in 3, 2, 1...

Not stacked with technical documentations on the AMX 10 RC but maybe that one will help you :

Whuuuut?
There is no rework regarding the armor.
It's just the turret of a tropicalised Leclerc on a Léopard 2A7 hull with an adaptator and a rework of how the two communicate together...


 
 
The later prototype was labelled as "standard european tank - french version" dunno about that one...

The design of the Leclerc allows a more convenient gun balance (on or very close to the trunnions axis).
This allows the minimize momentums.
The turret is balanced as well to control any momentum to achieve the same controls over momentums.
Turret traverse and gun elevation have high acceleration rate (~45°/s²) dispite the 30°/s max speed.
The autoloader allows a constant rate of fire whatever the tank is doing.
I'll stop here, I'll skip FCS and suspension because, they have proven their values.

The thing is none of the persons here can judge the value of any tanks because the hardware hasn't been shown into their worst conditions. Abrams, Challenger 2, Leclerc, Léopard 2 and others have just fired at worst on bumpy dirt roads with the crews doing all the SOP requirements to ensure a steady speed and minimise the vibrations.
No matter what the competitions or tests have shown, people always forget that there is a huge piece of meatware that seats between the seat and the handelbar that can f**k things up...
 
I won't hide that I consider the human loader as a risk at high speed high bumpiness. But in real combat, the pace of engagement is much slower than we think.

Not THAT close, don't forget the recoil!

This is a Leclerc turret on a Leopard -2. 
Trials on the firing range were good. 
 
The French 140mm is very different but is said to be proposed for the MGCS. 

Leclerc turret.
Trials were good

Meanwhile at Eurosatory 2018 :
 
The Euro Main Battle Tank (EMBT), a private venture project intended for the export market.

Let's start to quick the AMX-56 bullshit out of the window.
 

The french documentary with the original interview of the program manager.

I will look for my Satory catalogs for some vintage data.

Well it's just a certain nuance.
Obviously there is a stabilisation system but it is limited to the stabilisation of the line of sight (within the sights).
The turret itself has no stabilisation system.
A stabilisation system uses a set of gyroscopes located at specific points (hull, turret, armament).
The angular informations gathered by the different gyros is computed by the FCS which gives a set of corrections to the elevation and traverse mechanism (the most early stab systems where the armament remains to the same position no mater how the tank behaves). In addition the FCS adds on top of this another set of corrections related to the ideal LOF (later stab systems that introduces the concept of correction of the position of the tank).

On the Leclerc, the sight being how it is, the number of variables is kept as minimum as possible. You only compute the angular variation between the current LOS and the ideal LOF. The set of values is then dispatched to the "guidance system" (asservissements) which monitors the actual movement of the turret (traverse and elevation) and assess the need to power the electric motors or revert them into generators to brake the movement.
In itself the tank knows on its own the position of the differents elements (hull, turret and armament) with the closed loop elevation and traverse. The sight give the angle of the whole.

Hope it is clear. It's not a whole lot but we make this distinction.

The specs required a highly mobile tank capable to destroy any Warsaw pact (PAVA) tanks at long range with a high hit probability on first shot. This led to the crafting of highly precise system.
To be honnest with you there is no stabilisation on the Leclerc. The gun is slave to the ballistic computer which computes the ideal LOF from the stabilised LOS.
When reloading, the gun goes to the reloading elevation. Meanwhile the LOS is still stabilised to the direction of observation (in the limits of the mirrors amplitude). Unless you release the palm switches, the mirrors go to their mechanical neutral positions.

The gunner sight is mechanically mounted to the main armament. When the gun goes up and down; the sight bows up and down.
Since the both move along with the exact same angle, boresighting can be done automatically with a deviation measurement laser (AMX 10 RC being the first french AFV to be equiped with such device).
Crews do some alignments (what we call "harmonisation" where we keep the parallax in check), but that's not the bullshit stated by Sergei Suvorov where crews were forced to boresight everytime they move their tanks...
 
At the time engineers were open minded on what could replace the classical tank. Once they defined that their platform was still an AFV, they assessed every kind of compromise to take what was the most favorable and compatible to their specs guideline.
 
 
Fun fact regarding the tracks. They spent quite some time to switch to steel tracks. They initially used the same arrangement as the aluminum alloy tracks (the shape of the rubber trackpads were supposed to reduce the stomping effect). Surprise, surprise, the vibrations at high speed were strong enough to be a handicap. This explains why we transition from V2 (alloy) to V5 (steel). Apparently V4 was also a disappointment.

Even with V5 or DST 840 the vibration is quite awkward compared to V2.
