You need to remember for dug in troops these platforms are useful for bringing in ammo and food and water etc, and when operating on foot would be rather good for providing fire support, but most of these units will also have a BMP or BTR to support them as well, so this is essentially saying to a light infantry platoon that the machine gun guy operates a remote control and does not have to carry the machine gun and can now take thousands of rounds of ready to fire ammo with it and provide support.
The next generation of Ratnik has goggles with VR and video capability so mounting decent stabilised night and all weather optics on this gun mount means the gunner can hunker down somewhere and position his gun where he has good overwatch and he can deliver accurate long range fire and high volume fire when needed. A sniper and rocket launching version would be useful for engaging key enemy personnel and enemy armour and fortified positions respectively. these days some sort of air defence model for use against drones for troops in the field and in trench lines would be useful too I suspect.
