This game reminds me of Road to Moscow from 1984, though I only played it on the C64 in 1987, thanks to a pirated copy bought at the newsstand (yes, buying pirated games was the norm back then, despite the oxymoron). I was 12 years old and spent whole days figuring out the best way to defeat the ♥♥♥♥ armies in the Russian steppes. Good times!
