Welcome to our world( I mean, for those of us who've faced Ethereals)... nasty buggers aren't they? I try to avoid them until I can get my psi-evaluations.
One of the best ways of fighting an ethereal crew is to kill as many of them as you can before their psionics make mincemeat out of you. But this is easier said than done.
Tanks do wonders if you can deploy them safely. Psi can't harm them.
If you already have power armour, you might want to consider specifically arming your problem soldiers with standard rifles or pistols. These guns cannot puncture power armour, but they can hurt ethereals (albeit slowly). Laser pistols are great, but they can still go through power armour.
If you have flying suits, consider arming the problem soldier with an autocannon with HE shells. Not a heavy cannon -- it's too strong and will puncture a flying suit. The AC-HE shells are very mild in comparison. Your soldiers won't be 100% invulnerable, but it won't kill them instantly.
And now some tips for those pesky sectopods:
- They're weak against lasers. This goes without saying, I suppose.
- Alien grenades or high explosives do wonders if tossed into one of the tiles that the sectopod occupies.
- They're a heck of a lot weaker to stun bombs. When shot with one, they have a small chance of surviving it, but when it works, they drop instantly. Once they're down, they'll never get back up again.
What's more, you can disable multiple
sectopods with one bomb if they're all standing in a tight formation.
What a way to kill several mechs with one grape eh?
