I managed to finish a Sea Raider lair, but how am I supposed to take out the Tundra Bandits? I have a few troops vs. a dozen at start. Each bandit has a bow and can down me through plate mail in a couple arrows, 7 or so more arrows if they need to destroy my shield. If I finish the first wave I'm surrounded by the next wave that again whip out anti-tank bows and massacre what's left...

I've tried bringing companions, then Slaver Chiefs (nice big strong shields), and still end up wiped. Should I just bring several Rhodok shields, order my troops into a corner of the map, then stand there as an arrow sponge hoping they run out of arrows before I run out of shields so my troops have a chance to fight, or what?

In the field it's no problem but no cavalry, no cover, and having to be outnumbered and exposed to incoming fire from multiple directions while trying to cover ground in the lair is a little frustrating.
