Sorry to pull this out from quite awhile ago, but I had another thought for a defensive combat order.
I’ve been in situations a few times where an enemy fleet is following a ship. The ship loads mines and drops them right in the path of the incoming fleet.
I would’ve called this Evasive Pattern Epsilon, as it happens, because it is an Echo on the defensive instead of offensive. Evasive Pattern Echo could work, but confusion could ensue on the part of the Helm officer.
I do like both your proposals, @gabrielwade. Since EMPs are often fired first, I would argue that calling an EMP strike Maneuver Alpha would be understandable. The EMP-Echo could then potentially be named after the combination of the two: an Alpha-Echo, or it could be given another name.
