Earth 2150 Lost Souls - LC last mission - Mission 10: "PROTECT ESCAPE", Germany - level Hard

I have not seen any video walkthrou in Hard on YT so here there is my a small contribution. This mission is not so much difficult but it can be troublesome because AI respawned attacking stacks of units - are really ( so far probably the most ) numerous, while the resources are limited. Therefore, mindless fighting might run you out of money. There are a couple of optimalizations you can do for effectiveness: 1/ use a chokepoint in the north of the central base and retreat units that are being targeted/damaged by moving them eastward or westward. 2/ use sonic weapons at this place - alongside with electro guns. Sonic weapons were also effective while defending the (main ) southern base on more opened space. I did all LC campaign using electro and plasma guns but replaying this mission with electro and sonic weapons - this combination seem to be a little bit more effective. I am not 100% sure. 2.5 / LC artillery units at the chokepoint are very effective They were useless in the previous mission where you have to attack enemy base on elevated ground. In this last mission, these slow moving units have very high hit ratio.
