The BMD-4M is a new generation amphibious infantry fighting vehicle (IFV), not a modernized variant of the older BMD-3. It is the only IFV which can be dropped from an airplane using a parachute platform. The vehicle can be paradropped with all the crew inside, thus saving time for the assembly after landing. Launched from an aircraft, it can reach the assigned targets in a matter of minutes at a speed of up to 45 mph, opening fire from a range of weapons. The BMD-4M is able to cover over 300 miles without refueling.
The Il-76 transport aircraft can carry two BMD-4Ms. Once landed, less than three minutes are required to start the vehicle, manage the positions and arm all weapons.
The vehicle can also drive through the water. The BMD-4M boasts the capability of fording water sources and changing tactical approaches on-the-fly. On water it is propelled by two waterjets. The vehicle can traverse water obstacles without any special preparation. The BMD-4M can develop a maximum speed of 70 km/h on roads and 10 km/h afloat.
The vehicle has a length of 6m, width of 3.15m and height of 2.7m. The combat weight: 13.5t. It has a cruising range of 500km on highways. The ground clearance ranges from 130mm to 530mm. The BMD-4M is able to negotiate gradients of up to 35 degrees and maintain fire whilst in motion by traversing the turret and keeping the target in its sights. The BMD-4M has a crew of three: a vehicle commander, a gunner, and a driver. It can carry up to five troops.
