Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Moves quite fast even when stock
- Autoloader with a 5-second reload for ATGMs (fastest ATGM reload, reloads faster than most conventional tanks as well)
- Can fire on the move without restrictions
- Can carry up to 8 (4 9M117+4 9M117M1) ATGMs
- Commander can still fire weapons even if the gunner was shot
- Also can fire HE at enemy tank roofs by using laser rangefinder or AB aim assist
- Also has an autocannon which can be fired along with the main weapon
- Can act as a scout and also has thermal scope, smoke grenades and ESS, which can be used to scout or fight
Cons:
- Low armour protection, hull can be penetrated even by a 12.7 MG until movement modules are researched, which will protect BMD-4 from some frontal shots or even block overpressure
- Only 3 crew members
- Extremely awkward sight controls for HE - to even access it, user must swap main weapon to "secondary weapon" which disables the autocannon and MG completely
History
Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
