From what I’ve seen from other post and bug reports the current Leclerc’s have the amor values taken from one of the pre-series Leclerc that was tested by Sweden, and not their actual thicker armor values found IRL from Leclerc S1+
(Leclerc being tested in Sweden)
So if the Leclerc pre-series are ever added I cant see how they would help fill the 9.7-12.0 gap. As they wouldn’t be any different from the current Leclerc S1. It would just add more tanks to the all ready over bloated 12.0 line up that consists on 6 MBTs, 1 SPAA, 0 light tanks.
