There have almost certainly been satellite, submarine and other engagements too, they just aren't generally publicized by either side until 30-40+ years later.
Battles won by numerical superiority are usually won by defenders. If it's an invader, it's almost certainly early in the game. Even at the end of WW2, Germany wasn't invaded so much as it lost in France and Russia. The Allied rush to Berlin was an early aftermath. By the time supply chains necessary to conduct a protracted war have been committed, the true cost starts making invaders progressively less interested.
A more interesting concern is the major powers using proxies to demonstrate their new tech. If Russia sold Syria 10,000 drones, that might get interesting.
Sorry, no. Germany was very quickly overrun in 1945.
