Well i had a REALLY GOOD SNIPER (Marina) i spawned her at the building thats on the upper right corner of the map, basically right in front of the enemy forces, she took out most of the lancers and tropers, of course i used a supply character to give her more bullets.
after that i put all my lancers on a safety zone out of range of the enemys giant TANK and then i did not attack it, i just waited till it advanced a little and then, if im not wrong maximillian must shot a giant pillar thats on his way, when he does that hes weak spots are revealed (5 generators, 1 on the back and two on each side) then i used my lancers and welkins tank to take out all of the tank main machineguns so the lancers could get on top of the tank and shot the generator in point blank, also you dont really need to do this since you can shoot the generators with welkins tank at long range.
NOTE, if maximillian doesnt shoot the pillar to reveal his weakspots then YOU must shoot the pillars first in order for them to fall and get in his way, THEN Maximillian will be forced to shoot them therefore revealing his weakpoints, after that keep shooting every pillar so he is forced to keep revealing his weakspots. and keep shooting those weakspots with lancers and Welkins Tank.
SELVARIA
when she gets on the battle zone JUST IGNORE HER, and hide all of your characters except the TANK (she cant destroy the tank at this point in the game) si hide your characters because she will kill them in one shot at almost any range. and keep shoting the generator on Maximillian tank, because at this point you should have taken down enough pillars for him to be very busy shooting his main gun and revealing his weakpoints.
thats how i beat it, any doubts or questions ask me.
