Just put the same APDS against angled armor, something you find in any vehicle in this BR and you’ll see how worthless is the APDS. Glad, the 30 mm 2A72 is a coaxial, while the 100 mm is the main weapon, while in-game is the complete opposite. Use all the 4 missiles on the BMD-4/4M and you’ll be useless. The BMP-3 does have more but considering the long time of reload and more limited mobility and weight makes this vehicle no so good for rushing like BMD-4/4M can.
You can, if you got said vehicles, test it against most MBTs you find in this BR range, even the Leopard 1A5/A1A1, the 30 mm APDS 3UBR8 can’t pen without going for the angles on the corner of the chassis or the TAM 2IP without going for the missile. M60 and variants is the same thing, and worse the XM-803, MBT-70 and Kpz-70, try to pen those with the APDS. The only thing that makes the BMD-4/4M powerful is the 9M117M1, which, along side the mobility in exchange of armor.
The BMP-3 would be never similar to the ZBD-04A, the engine and transmission mounted on the front, external fuel tanks makes the survivability of this times more better than the BMP-3 which relies on the fuel tank as filter against chemical weapons like HEAT. The same is for the ZBD-04A but also protection against lower caliber kinetic weapons like AP.
With the OP @Viper_Zero using the document mentioning that the BMP-3 can use M929, when it can, it’s not the round in service in the Russian Armed Forces, but NATO members, probably on the vehicles mounting the 30 mm Bushmaster II Mk. 44 auto cannons and 2A42 auto cannons used by Slovakia, which, by a news article published in janes.com, mentions the use of M929 during trials in the BVP-M2 ‘Šakal’ with the RCWS TURRA 30;
Belgium’s Mecar and Slovakia’s ZTS-Special conducted validation trials in late April in Slovakia with new M929 armor piercing fin-stabilised discarding sabot-tracer (APFSDS-T) ammunition developed specially for the 2A42 family of 30x165 mm calibre automatic cannons.
The trials were held over two days at the Military-Technical Testing Institute Záhorie (VTSU Záhorie), and fired 240 rounds from the TURRA-30 unmanned turret fitted on a Sakal infantry fighting vehicle (IFV) prototype, and from a two-man turret on the BVP-2 (a locally produced BMP-2) IFV. The 2A42 cannons were fitted with new four-chamber muzzle brakes.
The M929 APFSDS-T ammunition is about 95% complete, a Mecar spokesperson said, adding that it is now being marketed to potential customers. The spokesperson did not reveal the potential customers.
According to a Mecar presentation, the M929 APFSD-T ammunition is 293 mm long with a 690 g nominal weight; the propellant has a 130 g nominal weight. The 235 g penetrator is produced from a cobalt-free tungsten alloy and the cartridge case is steel. Muzzle speed (at 21°C) is 1280 m/s. The tracer burns for 2.1 seconds, and the penetrator takes 1.7 seconds to fly 2,000 m. It can penetrate 50 mm of rolled homogenous armor (RHA) at 60° from 1,000 m, and 40 mm of RHA at 60° from 2,000 m. Its dispersion is <5 mil. Operational temperature is from -32°C to 62°C.

While ODIN mentions it can use the 30 mm M929 APDS FS-T ammunition, it doesn’t specify which country uses the said 30 mm 2A42 auto cannon. And that’s why I mentioned on my first comment in this thread “ODIN again fooling another soul. […]”
