So pretty much what he is saying is that in almost all the vehicles there are three crew which will all be stationed in the hull rather than the turrets of all the vehicles... armata, kurganets-25, boomerang-25 and boomerang-10... in the heavy, medium, medium, and light weight classes respectively.
Rather than develop three different families of controls and sensors and weapons (one for heavy, one for medium, and one for light) they have developed one set of controls and displays for all three crew and they have developed weapon and sensor suites... for aircraft the electronic suite of sensors and weapons and electronics is called avionics, but there is currently no similar word for ground vehicles, but that is what they have done... they have created a standard work station with standard displays and controls and systems for each crewman and each vehicle.
This means that a crewman from a light brigade who is trained on a Boomerang-10 MBT will be trained to use his 10 ton vehicle with its thermal sights and other more sophisticated sensors and aim his main gun and hit armoured targets at long range. There are three crew positions in his vehicle, just like there are three crew positions in the Kurganets-25 and Boomerang-25 and the Armata MBTs and he can be driver, gunner, or commander from any of the three positions in each vehicle. In the Boomerang-10 he might have a 57mm main gun with Kornet-EM missiles as a main armament, while the Kurganets-25 and Boomerang-25 and the Armata might all start out with 125mm smoothbores and the Armata MBT might later get a 152mm smoothbore as its primary armament.
Equally the main artillery vehicle will have electronics and sensors and weapons that suit the gun tube artillery role, but the Boomerang-10 might have a 120mm gun/mortar as a primary weapon, and the Boomerang-25 and Kurganets-25 might have the same weapon while the Armata will have a single barrel Koalition 152mm gun firing shells to 70km with GLONASS guidance. The electronics and sensors and equipment will be standard and similar though the weapons might be different in the different weight classes.
The point is that the three different types of vehicles in three different weight classes will have standardised crew positions that are the same across the different platforms.
The main difference will be role... artillery, air defence missile, air defence gun/missile, recon, engineer, MBT, IFV, APC, BMPT, Command/communication transport, NBC, TOS replacement, Rocket artillery, Ambulance, etc etc.
This means one factory can make the crew stations for all the vehicle families because they will all be the same.
Once a crewman is trained to use the crew station they just have to learn the role of the position to move to another vehicle or do another job within his own vehicle... the driver can be trained to command and operate the gun so the crew can operate in shifts during quiet periods.
Note the sensors to give situational awareness means that down in the hull any of the three crew need a 360 degree view of the vehicle from up high like they had their heads sticking out the turret... which of course none of them can do. They can't use actual glass periscopes because the turret is unmanned which means multiple cameras and optics and other sensors all combining a "view" around the vehicle that is transmitted to the work stations of the crew.
Now if you think for a moment that means that the crew in the vehicle don't really need to be in the vehicle so a transmitter with digital controls could be in a van controlling such a vehicle... this has the potential to have teenagers controlling the Russian Army vehicles using an upgraded Tank simulation program like Steel Beasts but using direct video feed and sensor information from an actual vehicle in the field with the operator on a computer perhaps thousands of kms away operating it in near real time.
For mine clearance or IED disposal it means an engineer vehicle with all sorts of robot arms attached to it can be driven up to even the biggest IED... perhaps a wired up 1,500kg aircraft bomb, with the crew 1km away in a van or another armoured vehicle.
Indeed you could have an IFV modified so the rear has extra crew stations to drive mini vehicles armed with RWS and filled with ammo to attack particularly hard enemy positions that are unmanned, while a recon command vehicle could have a variety of land and air unmanned vehicles that can be controlled in extra crew stations inside the recon command vehicle... which could simply be an IFV design with rear troop compartments replaced by workstations and comms equipment.
The BMPT could be an IFV with the rear troop compartment filled with an auto ammo handler to allow more ammo to be carried and used for the medium and light vehicles.
Or it could be a mortar carrier modified to allow a direct fire mode and more direct fire weapons...
There are a range of potential options... it is very exciting...
