i just hope i will not screw up everything.
You wouldn't be the first. If something is too armored, use electricity or laser for their armor-ignoring powers.
Advice (that applies to the majority of the game anyway): Cattle Prod works against most things, but is 2-handed. Resistances are on the wiki, and should be accurate still. Hopefully gals are all trained well enough that you can walk up next to an enemy to mess up their aim (but it takes 9 stamina, so don't run too much if you can help it). And chase down enemies if you can/want (do we still have the 400 speed thing that can only chase harvesters, extractors, and slower buildings?), because most ships land. I'm pretty sure we can't handle bases yet. If you can capture academy drones with electricity damage (it also ignores the immune to stun tag), you can disassemble them for more superconductive wire, so we can make more chainmail. Plus, they take up beast den space instead of prisons, so there's not as much worry about running out of space.
I rearranged equipment quite a bit, and switched people to and from underwater missions, not to mention putting wounded gals is basic clothing to use their armor... So yeah it's just a senseless mess, feel free to change it all
Also, we should probably be keeping the gals back at base armored, in case they need to defend the base.

Edit: How close are we to the Dr. X missions? We should be able to/have done the first one, which is a lot of fun if you've trained melee well, and a LOT of loot/hostages. Sure, enemies might get back up after getting punched out (you're unarmed), but also you're several floors away from them by then.
