Moved into the Clan era in a campaign and my little merc company regularly faces off with a entire clan trinary every battle with only a Lance selected. Not sure what is happening but against everyone else, pirates, other houses etc, the fights are never that bad. I mean even a Clan star is equal to almost my entire company in BV. But facing a Trinary is hopeless.
Not a huge biggie, I can always delete units before entering the battle is just a hassle really. Just feels like cheating as I can easily delete the most dangerous enemies if I so choose for all the easier salvage.
