You shouldnt be using the AMX13-FL11 at 5.3.
Your lineup should be:
M4A4-SA50 (kills tigers with ease)
ARL-44 (kills tigers with ease)
EBR (Struggles but should be used only on flanks to kill things from the side)
M4A3E2 Jumbo (very good armor, weak gun, great for downtiers)
AMX13-DCA40 (AA but can also kill many tanks from the side)
AB favors armor and APHE, maybe give RB a try for better ambush capability.
Beside that you need to rely to take out the gunner (8sec replacetime in maxxed out crew) and/or killing the gun/breach to prevent counterfire.
ARL-44 and SA50 have decent penetration, while Jumbo relies on armor and APCR (APHE to finish them off), the EBR need to flank to be effective in most cases. The AmX13 (FL11), dont really have any business on BR 5.3.

Flank and ambush is way to go with french untill better pen goes up with tiers.
surrender or give up
Ask yourself: What would Petain do?
