The missiles are launched at near maximum speed from the get go, which makes them ones of the deadliest at the rank (as many missiles at the BR start at around 250 m/s at best), but also make them mostly unsuitable for trick shots of any kind and require direct launch. Overall, they can be used to harass other tanks out of cover (including ATGM carriers) or fired along with the autocannon to blow up light tanks in general melee range (although it is very awkward and slower than with the BMP-3). The projectiles fall very slowly, but they are also very small and will often squeeze in-between ERA bricks and hit the enemy tank roof, causing overpressure damage and destroying the target. Unlike with the BMP-3, it is also necessary to swap primary weapon to "secondary weapon" to be able to aim HE precisely.

HE shells are mostly designed to be fired in a mortar fashion and for comfortable use it is necessary to install laser rangefinder or to play in AB mode. The ammunition choices are: Slow HE (3OF70), super slow HE (3OF32) and Tandem HEAT ATGM (9M117M1). Gun itself can bring two different ammunition types into battle, although the choice are limited to chemical energy shells. Without upgrades, it will not put itself back on target in time, and the tank can't sustain even accidental hits unlike the BMP-3.

While the gun is stabilized, it is not a very good idea to rush uphill at full speed until gun drives were upgraded as the gun has poor depression and kicks upwards when the tank drives uphill. However, its autoloader can load ATGMs as well, removing the 28-second reload penalty which makes the BMP-3 unsuitable for skirmish, at a cost of 1 second of reload time overall. The 100 mm of this tank is near identical to the one on the BMP-3. This, unfortunately, breaks the weapon layout, and the 30 mm becomes unusable until the control scheme is reset. While this is fine if the BMD-4 user uses an ATGM, but the only way to swap scope to acquire aim assist for the 100 mm gun to land precise hits with HE shells is to switch from the main weapon view to the secondary weapon view. The aim assist and scope is, therefore, displayed for the 30 mm gun. The autocannon counts as the main weapon and 100 mm is fired with the "additional weapon" keybind. Despite the low fire rate, it still fires faster than the one on the Warrior and if the player fires first, it can neutralize many light tanks at close to medium range before the BMD-4 is knocked out from their retaliatory fire. There is only one rate of fire option for the cannon - which is relatively slow at 300 rounds per minute. The 30 mm fires the same shells as the BMP-2 autocannon does and is identical to the one on the BMP-3.
It is easy for planes to strafe the BMD-4 from above for the same reason. The roof is vulnerable to even HEAT overpressure and turret hits with chemical shells are very dangerous for this tank. Researching mobility modules adds some of them to the front of the tank, which reduces likelihood of taking overpressure damage from ATGMs and increases chances of blocking autocannon rounds when they hit the hull. Autocannons are very likely to just shred this tank instantly, but how soon this happens depends on enemy attention span, autocannon rate of fire and where an enemy aims first. The front has an adequate armour thickness, but the upper front plate of the hull is more vulnerable than the turret or the lower front plate and allow for penetrations with 12.7 mm MG, even from afar.
