I use to support the BMP3 IFV for the AFP, after the action in Chechnya with all the smoke in them i doubt it could fire on the move. Why not just invest in the ACV-S of Turkey a stretched version of the ACV based on AIFV something we are more familiar with and will be easier to maintain. Just add a turret armed with 90mm gun for commonality with the Marines V-300 / LAV-300
I think It have been discussed before that there are certain problems fitting a turret w/o extensive structural changes on the Vehicle.
Much better option is to have ACV-S With Grenade launchers Or Mortars (for Fire support)
and TOW missile mount (for anti armor).
Better Option is to Just get more V-300 / LAV-300 with 90mm gun (for fire support) then TOW mount (for anti armor)
No need for extensive training since we are already familiar with the Vehicle. Will not Strain logistics and maintenance chain since there is already an existing chain for it.
For Added protection, additional Metal/Ceramic plate armor or RPG cage against RPG's and anti materiel weapons.
Or just Install Trophy active protection system from Israel.
