This is an hypothetical scenario with symmetrical map and units, so it's supposed to be a balanced campaign featuring naval, air and land warfare, with a sprinkle of "economy" due to bonus to reinforcements tied to strategic locations.
Both militaries advances into neutral and friendly countries. Blue military seems to be a bit spread out, and it takes a bit too much losses and time to take cities. Numerous air raids, including airport strikes; my aviation downs a lot of bombers, albeit my own losses are significant.
My own advance is a bit more organized, taking White and Black with negligible losses and keeping my Corps in cohesion. I focus on air superiority, downing way more enemy planes. I keep some of my medium bombers on Interdiction strikes, but with little effect. I want to whittle down their own aviation first.
I decide to hold the northern front with just the 1st Corps and some elements of 1st Army. There is a long stretch of desert before the next Yellow city, I don't expect the enemy to push seriously there and I don't want to waste too many troops to defend from weak attacks.
The central area will be crucial, so I put 2nd, 8th, 10th and 19th Corps there, behind the river encompassing the area, with my Tank Corps in reserve. In Turn 4 the enemy swarms Brown territory making contact with my MLR over the river. One of their heavy armored division tries to exploit a gap in the line, but it was a trap: just behind my Tank Corps was waiting for them, and I can quickly encircle and destroy it. In the first pitched land battle of the war, Red claims a crushing victory.
The Green territory is another strategic area, being it my ally and placed on the most direct route to enemy capital. I intend to defend it if possible, so I send 5th, 30th and the Marine Corps to defend it, alongside with a LOT of heavy artillery of the 2nd and 3rd Army. I place this strong concentration of forces around EE-34.
The Blue Navy makes a run for it, attacking mine in front of an ex-Black port. Thankfully, my ships hold their own and during several turns of fierce battle they ultimately kill the Blue Navy off. In Turn 4 the enemy aviation tries to destroy my ships from the air, but in a series of MASSIVE air battles (hundreds of bombers, thousands of fighters for each side) I emerge victorius.
Blue advance is in full effect in central Brown area, but rather disorganized: I manage to encircle an Infantry Division that made contact with the southern arm of the MLR, supported only by a single artillery Division. My troops are digging trenches behind the river, with few gaps guarded by armored divisions.
An armored assault along the northern coast is similarily isolated, and the attacking unit encircled and destroyed.
The Blues also strikes deep in Green territory, making contact with my positions around EE-34 and flanking them with several divisions that manage to slip south hugging the western coast. Fortunately I have several reserves there, and with the help of heavy artillery I manage to cut the enemy front and maybe cut off supplies to the troops headed south toward CC-39 and AA-42. Infantry reinforcements are inbound, but the enemy penetration is worrisome and I have to hope they will turn back north to try and break the encirclement.
