Chương 281: Bulgaria Surrenders

The difference between modern combined arms warfare and static trench warfare of the early 20th century was like night and day. Especially when one had complete and total air supremacy over their enemy.

There were three grades of air control in a war. On the lowest end there was Air Parity, which meant that airspace was for the most part contested between both sides of the conflict. In a more tactical sense, this meant that neither side could support their ground operations without having to suffer dearly for it.

After Air Parity was Air Superiority. In other words, one of the two combating factions had a significant advantage over critical airspace, allowing them to engage in air combat operations that could support their ground forces.
