I'm going to assume what you meant by "Launch strikes on Aurelian ships" is with drones, but please, for the love of god be more specific. You have failed to specify how you're trying to sneak by, like what, are they tiptoeing through the void of space? Just magically being invisible? One does not simply "sneak through" an active frontline. Also they're utterly fried again, stop sending transports into hostile territory, it doubtlessly gives almost everyone in the CBMV second hand embarrassment. One flyby with any orbital defense station and you're COOKED. Also there's not really avoiding them because you're charging at planets with unescorted transports and no space superiority or prior attacks. As for the main front, your 20 billion soldiers aren't helping the situation, they're just garrisoned on the ground (At least I hope, please, please do not say you're troops are trying to fight warships in space :sob:) watching Marosian combat vessels get cooked because they carry an ungodly number of explosives. Also 135 million to build a space warship destroyer/cruiser sized is DIABOLICAL, the USN Freedom-Class Littoral Combat ship (Frigate/Corvette sized, also with far less sophisticated technology than a SPACE WARSHIP) costs 362 million to build. Aurelian warships appear to have some capacity to carry fighters, so those would pick off drones preemptively, as well as any AA systems they may have. The Aurelian destroyers quickly discover that there exists many key spots (Missile storage, plasma storage, etc) where if a Combat Vessel is hit it suffers the fate of the HMS Hood, and hitting said spots would be prioritized. With the Marosians already suffering huge soldier casualties from the opening attacks, Aurelia would make it key to inflict as many casualties as possible to break down Marosian resolve and war support.
