[X] Plan String them out
-[X] Inform the Alliance?
--[X] Yes. They're impacted by this, and you're a formal member now. This is no longer the time to hold back.
-[X] Call for the Terminus Joint Fleets?
--[X] No. This isn't the kind of battle they train to fight, and you have yet to thresh out a joint command structure. There are also the obvious political reasons not to call for help on this particular issue.
-[X] Who reinforces Maroon Sea? Check all that apply.
--[X] 1st Battle Fleet. You need firepower, you need it now.
---[X] Both battle fleets are to conduct withdrawal through the Relay to Attican Beta once insertion of raiding fleets is done.
--[X] 1st Raiding Fleet. They will (in part) get there fastest.
---[X] Upon insertion, the fleet is to assume raiding duties.
--[X] 2nd Raiding Fleet. They're not in a frontline system.
---[X] Upon insertion, the fleet is to assume raiding duties.
--[X] 3rd Raiding Fleet. They're not in a frontline system, and Mordin is one of your greats.
---[X] Upon insertion, the fleet is to assume raiding duties.
Since I'm not seeing any plans yet that seek to deny Rachni the fleet battle, I've drawn one. It's not without faults, relying on shellgames to an extent - however, I consider the window between deployment of 2nd and 3rd raiding fleets and withdrawal of battle fleets to Attican Beta small enough to be an acceptable risk.
Now, what the plan does is let Rachni have an experience of a whole lot of raiders harassing their forces, assuming this is not a proper large-scale assault aimed at Caleston Rift. If it is? Well, then we retain our forces to deploy in reaction to that, and TJF, being warned yet not burdened by our demands for more fleets, probably can hold onto Caleston.
