Formation Zones for surface and submarine units (air are treated by loadout/patrol type)
0 - Main BodyMaintain position relative to group center
1 - AAW Ring
Maintain position in assigned sector(s)
There is no value in assigning units to multiple sectors in the AAW ring
2 - ASW RingSprint and drift around the assigned sector(s)
3 - Picket Ring #1Meander around the assigned sector(s)
4 - Picket Ring #2Meander around the assigned sector(s)
5 - Picket Ring #3Meander around the assigned sector(s)
What to do when a unit is assigned to multiple rings (i.e. a sector in ASW and a sector in Picket #1)? The behavior of the inner-most ring in the selection will define the behavior. ASW + Picket #1 selected will result in Sprint & Drift.I think any cross-ring assignment should be treated as a picket, meandering around the combination of sectors.
Currently formation-keeping will not change the heading of a unit. This needs to change.
