This would be a Heavy Mechanized Drone guarding a bunker entrance/military base along with soviet ground troops and artillery.
A few examples of Medium Mechanized Drones, this particulair one is controlled by Humans. These Drones are already fully trained and available for combat unlike Light Drones therefor they patrol the land for hostilities and clean nuclear waste untill they are needed in battle. (They would be in groups and supported by some ground troops as seen in the picture, they would patrol around towns and particulair sites of interests. A location for a new mine or city for example, but they wouldn't be that far away and available for military action if needed. Not like I would have to randomly scan my entire territory and pick them out one by one.)
Absolute terror for robots, this device creates and electric pulse that disabels any machinery it targets, one of the backbones of the current army. Any robot/drone attempting to attack were this thing is located will be shutdown rather fast, this would be a high priorty target for enemies to disable especially when that enemy's army consist mostly of robots.
A few soldiers up close, with protective armour. I suppose these could be special/elite units.
Another example of a Medium drone, this one is also controlled by a Human. A helmet will be available but in the picture he doesn't have one on at the moment.
Some more Soviet Troops up close.
Soviet super heavy tank, used in the defense of strategic points. Act as a mobile bunker, all turrets are turnable and pack quite a punch. Equipped with rockets as well, this super structure is capable of reaching a top speed of 30km. The tracks are currently unprotected but on the field they come with sloped steel armour, controlled by a 14 man crew.
Soviet super warplane, equipped with 6 heavy anti-ship rocket launchers. Capable of taking down the most modern ships available, the sheer power of the rockets makes them highly effective at bombing runs as well. Capable and not limited to destroying, bunkers, tanks, aircraft, drones. (Rockets can be equipped with nuclear warheads.)
Soviet Multi-purpose helicopter, capable of carrying rockets and heavy machine guns. Can be used to protect convoys or attack military strategic points, preformance is great. Highly manouvarble, capable of both transporting troops and acting as a gunship. With it's excellent armour and very high top speed of close to 350km an hour, it is a force to be reckoned with.
