Challenge Final Battle routed in 5 days! [Advance Wars Reboot Camp LTC]

Just like in the original game, The Final Battle versus Sturm can be routed in 5 days in the hardest difficulty mode. Its Meteor targets the most costly diamond area (centered into one of our unit), his units being counted as negative value.

D1: Max forces are switched between north and south for more efficiency. One tank is sacrificed for having good AI position.
D2: We destroy all bombers (to make it rebuild) and most fighters. We bait the Meteor with a 40k diamond (2 MDs + 1 AA), be careful with the other units position.
D3: We destroy all AAs and almost all bcops (to protect our air units). Andy's COP is almost useless but allows to get last bcop retreat. Instead of building a Tcop, it's possible to move the 4hp inf on the same airport and sacrifice it to appeal MD (and build a southeast mech instead). The southwest apc appeals tanks in range of Max D3 tank.
D4: Andy's 4hp inf is useless. His tank is moved east for the case where Sturm builds a tank in his southeast base (which didn't happen here). Thanks Eagle's fighter, we create a perfect bait for Sturm's meteor of 81400-16000=65400G for targetting its own MD. It's also possible to build a bcop for the bait (if you didn't build tcop at D3).
