I don't think the French themselves used the 105 and they were all meant for export. Belgium and Argentina are the only two nations that actually fielded the AMX-13 105 to my knowledge. I believe they had some mild issues with the possibility of damaging the turret after firing.
I drove the AMX13 in 1980/81 the artillerie version and we carried the 105mm howitzer... it gave with gunpowderload 10 one hell of bang.We had to secure the vehicle with extra blocks behind the track in additiion to the handbrake.
Imagine being a US soldier having to face off the vehicle (IS-3) that was built specifically to destroy all the German tanks that everyone feared so much during WW2. German tanks were scary but imagine being the GI who was unlucky enough to encounter the tank that destroyed all those German tanks that he feared so much. Nightmare scenario.
Челленджер конечно впечатляет. Гигант. Но Ис-3 в свое время был самым пугающим для противника. Думаю с современным обвесом и начинкой он и сейчас был бы грозным оружием
