O hai! I've been lurking here for the past couple of... years? Jeesh, time flies when you're waiting on your next fix (read: get a ****ing move on already with chapter 4
).
To me the Sol war resembles the Finnish-Soviet winter war of 1939-40:
It lasted only for 105 days (GTVA needs to keep this short because of Shivans).
The Soviets expected an easy victory and actually believed they would be greeted as the liberators by majority of Finns.
The Soviets had a massive numerical and material advantage (kinda like the GTVA).
The Finns were way more motivated, more skilled and more mobile where the strategic situation allowed for mobility (UEF are certainly the first two but the mobility is debateable).
For the first 2 months or so the Finnish defences held anything and everything the Soviets could throw at them, but at the end of January 1940 two things started to happen: The Soviets adapted their tactics and the combat fatique of holding the line for 2 months straight, with minimal to no downtime, began to dramaticly decrease the effectiveness of Finnish troops, along with casualties of course (kinda like the GTVA has been doing under Steele and kinda like the UEF aces getting killed one by one because of not enough downtime etc).
And the conflict was (one of) the precursors for a much larger conflict, the WW2 (Kinda like the Sol war will likely spark the win all, end all conflict for humanity)
I see a lot of similarities also in the mindset of the GTVA pilots and the Soviet soldiers. Both are the product of a totalitarian government, brought up to believe that they are surrounded by an existential threat, self sacrifice and dying for the glory/survival of the state are high ideals. Both also are lead to believe they are liberating an oppressed population.
