OPERATION COUNTRY BLAST///: With the invasion from the east being stalled greatly due to the heavily mountainous terrain, including from the southeast, meanwhile the south has been easy to invade since the terrain is far flatter, we will focus there since it would be a straight shot to Nashville. Our forces will be regrouped, additional troops from the eastern front will be moved to this front while military equipment such as tanks, artillery, armored vehicles, etc being shipped to all areas will now be focused here so we can prepare for a powerful push up north into Nashville. Once our forces are in place, which shouldn't take long since we've already started the invasion, we will begin the push. Our focus is capturing Nashville, so we will commence a blitz-style campaign up north, through the flat terrain, not harming any innocent civilians so we don't look evil or anything like that, while air units continue targeting Tennessee military bases, weapons depots, airfields, etc to weaken them while our forces march on. Forces in the southeast will do slower advances to keep the Tennessee military from thinking we are putting everything on Nashville so they can stay divided. If we notice they are taking forces away from the southeast to aid Nashville, we will immediately begin a hard advance in the southeast to force them to focus there again. Their supply routes will be bombed, any river fortifications will be bombed if possible to ensure we aren't slowed. Intel agencies will work to find such fortifications using satellite imaging as well as other technologies that can help with locating things (I fail to remember what else...) so we can bomb the right places. Our drones will also be launched for smaller attacks so we don't have to risk expensive aircraft every single time we want to commence air attacks.
@Fraternitea for the map(s)!
