1. I need to be indoctrinated more first with Russian revanchist ideas first especially if I knew people who knew a time when the states that split were once Russian.

You won't surrender if you'll get executed by the Ukrainians for trying to surrender. At least, a sane person probably wouldn't want to risk it. Better to risk dying in battle than to get guaranteed death as a result of you trying to desert.
