Assault rifle/SMG formations aren't just your bread and butter, but also half the toppings. You're going to use them a lot.

Unlike rifle echelons, which come in many forms, MG echelons are relatively straightforward: They mow down enemies. Ideally really quickly, because they have limited magazine sizes and are sitting ducks while they reload.

The way construction works is by giving various doll and equip classes resource thresholds, within these thresholds, anything can drop.
