All Leclercs should either see their BR reduced to 11.0.
Alternatively they could receive a new round to keep up with top tier.
The myth of the Leclercs being a “jack of all trade” has to end. At least the second part of the idiom is true: the Leclercs are currently masters of none.
It would be okay if the Leclercs had something else to compensate for it, like very good armor, but it is sadly not the case. To this day I still don’t understand why the STRV-122s, the most armored MBTs in the game, have a better round than the Leclercs, which are among the worst armored MBT at top tier.
There are 2 solid choices for a new round :
DM53 :
Although Italy never bought DM53 shells for their Arietes, Gaijin decided to give DM53 to the Arietes to try to keep them somewhat relevant at top tier. This obvious balancing decision could definitely be applied to the Leclercs since both Ariete and Leclerc perform similarly.
Fired from the Leclerc’s GIAT CN120-26/52 L/52 cannon, this would result in a muzzle velocity of about 1730m/s and penetration of about 645mm, which is in line with the Leopard 2A6/7AV penetration of 652mm (DM53 round), the Type 10’s penetration of 615mm (Type 10 round) and the Abrams’ penetration of 629mm (M829A3 round).
SHARD :
Another option could be the newly qualified SHARD round.
This round is made by NEXTER, the same company that developed the Leclerc MBTs (it used to be named GIAT).
Courtesy of @Laurelix, when fired from the Leclerc’s GIAT CN120-26/52 L/52 cannon, this round should reach a muzzle velocity of 1720 m/s. Its 775mm long WHA penetrator should result in an estimated penetration of:
720mm @ 0m (0°)
421mm @ 0m (60°)
-
668mm @ 1000m (0°)
390mm @ 1000m (60°)
So, a 20% penetration increase over OFL 120 F1 at 1km.
Then make the OFL 120 F1 a level 1 modification on all Leclerc variants (replacing OFL 120 G1), but give these vehicles access to DM53 or SHARD as a level 4 modification.
Otherwise, just put the Leclerc to BR 11.0. They currently aren’t a credible choice in the face of other top tier MBTs, especially the most armored ones equipped with spall liners such as T-80BVM/T-90M, Leopard 2A7V or the STRV-122s.
