Shamelessly copied from KR, because I can't be arsed to redo this

Basics of Defence Drills + Enemy List and Reward List

Same as the last three chapters. No changes in my echelon from 1-1. Go to that post if you want to see it.

No changes from 1-2. If you want to see my setup in detail, check 1-1's post.

(As always, if you don't want to see the introduction bs, you can skip down to the strategy section for the meat of the guide.)

Because I seem to answer this question constantly despite the sources on them, a quick guide to completing the kill based weeklies:

Before we get into the details of how calibration and enhancement works, let's first get around to how to unlock them. Both functions are accessed from the research menu, which you unlock at Commander Level 12. After that, you need to complete World 1-4 Night for Enhancement, and 2-4 Night for Calibration. Unlocking those is done by completing the story and subsequent emergency chapters,

Because shotguns were implemented and people kept asking how armour and such worked. Also because night battles have been a thing.

There seems to be a bit of a lack of understanding from newer commanders about what night battles are. Some may even think it’s this scary thing that’s fairly hard. Truth is, they’re very simple.

There are a few small changes between day and night battles. You have no command center, so you don’t need to worry about that being taken and you also have a limit on how many echelons you can deploy at a time.
