No, the .50 SLAP does not work on IFV's like the Bradley, Warrior except possibly the rear armour, don't know if they have tested against the rear armour. I know the Strf90(CV90) has been tested against various .50 SLAP and API rounds, especially against the rear armour, and the rounds have failed to penetrate. I'm also skeptic about it penetrating the BMP-3. Remember, the original BMP design is from the 50's and 60's, just like the M113, while the BMP-3 is far newer.
