It's the same outcome, the achievement is just for bragging rights. Not looking for too many spoilers or details - but does it change how the story proceeds in the next chapters? Looks like it would be hard for the story to progress as it does naturally if you eliminate all the enemies. One thing that really helps for getting the achievement is to do it on the lowest difficulty. The other thing to keep in mind is that the AI Cannons have 3 range, but yours will only have 2 unless you have the range upgrade for them. Seargent's uniform-more capacity is always good early game. Stacks with spear using unit traits as well. Abygale with two dragon units can eliminate a cannon squad in one go, so put her on one side and MC and Diana on the other. Sayunari war pike- good +15 bonus damage against cavalry early game when it matters most and ok stats to go with it. Archers help a lot on that, as do Stealth units, since both can attack the Cannons in the back row without having to take out the Sentinels first. Cannons can't attack back if they're defending, so you have an opportunity to eliminate them without them damaging you.

Then I prioritized attacking the cannon units and letting the non-cannon units attack me instead. Two healers helps a lot as far as keeping up with the damage dealt. Originally posted by Lyre:I made sure the MC, Diana, and Abygale all had two healers in their group.
