I wrote a post here detailing a number of Soviet events related to People's Militia Units that could be added to the game. I think additional and entirely historical PMU events that provided free units are a better fit to what the Soviets need than extra income. Also I also don't want to insult, but have you tried boosting convoy percentage to increase income to the Soviets from UK and from US to UK? From what I've seen, the two combined provide a fairly chunky boost to Soviet income especially in the critical (in this game but not in reality) 42 to 43 period.
The historical route to solving this issue would be to weaken supply throughput on muddy tiles further, especially in occupied territory. This would more accurately capture the situation for the Nazis on the Eastern Front. David Stahel, David Glantz and Robert Forczyk all indicate in their operational histories of the eastern front that mud (and in the case of Stahel, Nazi refusal to acknowledge logistical limitations and emphasis on the supremacy of will) was a substantial limiter. This is not currently represented in game. Winter also has too large of an impact on offensive operation and continues to parrot postwar Nazi propaganda about being defeated by the climate rather than the Soviet military (best understood as a variation on the stab in the back myth from WWI). While it should definitely reduce mobility if not prepared for it, it should not substantially impact offensive capability otherwise.
The Nazis should definitely outnumber the Soviets at the start. On the border on June 22 in 1941 they had a substantial advantage in manpower and material (especially when including the surprisingly large if ill equipped forces of the Axis minors). Around 4 POINT 5mio Axis soldiers attacked around 2 POINT 5mio Soviet defenders. Only after substantial time and the immense crash mobilization that the Soviets underwent did they manage to amass a comparable force in manpower. They then lost this parity at the catastrophes (as Lev Lopukhovsky calls it) at Viaz'ma and Bryansk. And only later in the war did they rectify the real disadvantage in material (chiefly trucks and planes, a substantial disadvantage in both that jointly led to substantial impairment to operational mobility and performance). At no point prior to late 44 did they substantially outnumber the Nazis on the front as a whole. Only by bleeding secondary fronts of all forces and concentrating them into shock armies assigned to specific attacking fronts did the Soviets manage to achieve overwhelming superiority on key frontages. For instance, during the critical counteroffensive against Army Group Center in 41 (during which snow fell on both the Soviet and the German side of the front....) the Soviets barely achieved parity in manpower and were still short of material.
This game also continues the myth of the elite Manchurian units, but I'm not getting into that. Most of the forces transferred were simply equipped to to the prewar standard, largely with obsolete equipment. It is only in comparison to strung out Nazi units and the much reduced TOE of 41 to 42 for Soviet units that they could at all be described as well equipped.
Cities are also far too easy to attack with tank units. I'm not sure why this is at all effective. It has not ever been the case that an armored force was successful in direct assault against a determined and reasonably well equipped/supplied opponent in urban warfare without exceedingly high expenditure in lives and material. Meanwhile in this game I tend to start urban assaults off by smashing the enemy with heavy tanks, an utterly asinine decision from a historical perspective but wildly effective in game terms because it ruins enemy readiness/morale and guts entrenchment. In reality, a concealed 53-K or soldier with an inflammable projectile would have no trouble dispatching a Tiger in the close combat situations enforced by urban fighting. In game, the Tiger would gleefully prance around annihilating everything. The entire scenario feels absurd, as if it were straight from the fevered mind of Hitler himself. Forczyk and Dougherty both detailed the critical nature of small infantry units and combat engineers using infiltration and a hearty helping of explosives to defeating the French fortifications at Sedan, and Glantz says the same regarding Soviet annihilation of Japanese fortifications in Manchuria. I have never read similar comments about SS actions at Kursk (frontal assault with heavily equipped units against Soviet units equipped largely with 45mm and 57mm guns) or Nazi actions at Stalingrad, yet here we are.
edit: And once again this awful forum ate my post because it happened to have a link to my prior post on this forum. Whoever wrote that rule for this site should be sat in a dark room full of garbage to think about what they've done.
edit: Apparently this forum thinks that June 22 OF 1941 (minus the OF) is a phone number and eats my post. Whoever wrote the regex for that is an incompetent gibbering baboon and should be ashamed.
