First unit you can unlock is the fast unit (stardust
sentinel). It’s considered a flying unit
but artillery can hit it so it doesn’t matter.
It has a bonus vs. range but range units are it’s kryptonite as they
have contact ability. If your red attack
defense is good then you’ll be fine.
Next unit you can unlock is the light melee unit (cosmic blade
master). I only use these for excavation
sites on the continent map. They’re not
good.
At this point you’re going to need the SASH special goods
dark matter to open research so things get a lot slower.
The next troop type you can unlock is the short range unit
(gravity gunner) and this is the go-to unit.
It has contact ability and 2 units+6 rogues then 3 units +5 rogues at higher
attrition makes fighting in SASH easier than SAT.
The heavy melee unit (galactic juggernaut) is the next
unlocked unit and it’s bad. It moves
last (initiative 16) so it gets hit by all the other units before it
moves. It has force field ability so it
can take some hits but it’s useless in my opinion.
The next unit you can unlock is the long range (dream dust
blaster) and it’s good. It has a high
base damage and power shot which ignores all other abilities except terrain
advantage.
Once this unit is unlocked use 2-4 units + rogues until
attrition climbs then switch to range units as described above.
