    descending speed between 15 m/s and 20 m/s

    I’m assuming that they put larger parachutes on the thing before putting humans inside.

    Also, the vehicle itself could easily land in a location from which it couldn’t be extracted (either because of a lack of suitable equipment or because of the location being virtually inaccessible). Several experiments were done in the 1970s in order to find a way to circumvent these limitations, including dropping the BMD with the two key crew members, the driver, and the gunner, seated inside the vehicle during the descent.

    That, on the other hand, seems harder to resolve.

    “On the down side, instead of losing a BMD in an inaccessible swamp, we’ve now lost a BMD containing several soldiers in an inaccessible swamp.”

    “On the up side, our responsibility only covers air logistics and ends once we’ve delivered the hardware to the soldiers on the ground. Now it’s a ground forces problem.”

      As the BMDs are fully amphibious, it should be able to be driven and move after landing even in a swamp. Then, the core crew can collect the other crew members at their individual locations.

      Landing at 20m/s, which is roughly the equivalent of jumping down 2 meters. Without bracing, or seeing when you hit. While sitting.

        Apparently, the solution to this is retrorockets -

        Once clear of the plane a single large main chute opens. The deployment of the main chute triggers the deployment of four long rods which hang beneath the pallet. As soon as the rods touch the ground fires, slowing the BMD to a descending speed between 6 m/s and 7 m/s and giving it a relatively soft landing. This system entered service in 1975 and allows a BMD to be relatively safely parachuted with both the driver and the gunner.

      Love this meme, as it needs little translation across cultures/languages. Keep being excellent and we’ll make you the Shah of Moscow.
