For reference from an actual civil war, here's a map of Syria's administrative provinces:
Here's the map of controlled territory by factions in 2016, during the height of the civil war:
You can see that state lines make little difference. It's more relevant where the oil fields are, the geographical features (rivers, deserts, mountains, etc) & where the population centers are.
every US state nominally has an army answerable to its state government. it's a bit silly to believe these would be 1:1 in an actual civil war, but there's reason to believe in a higher retention of regional blocs over a free-for-all.
This is true, and to be fair, the Syrian "civil war" wasn't really a civil war. Insurgents flooded in from Iraq, Jordan and Turkey en masse which is why the ISIS/Rebel (same thing really) strongholds and territories are along these borders. Foreign governments like US, Israel, Saudi Arabia, Qatar, UAE, Turkey all poured billions into various terrorist factions, and shipped in heavy weaponry. Russia, Iran, Hezbollah all got involved on the side of Assad.
