So some of the best strategy games in my opinion are ones where orders are considered separate from the units that are assigned to them.
I imagine being able to set up a command group with no ships in it, assigning objectives to it, then assigning a group of units to that group and having them execute those orders. This would open up a huge number of other great things you could do with these command groups.
When preparing a set of orders, you could see a list of orders and options for them onscreen. You could reorder, adjust and modify orders without having to redo the entire chain of orders. If you think the order you kill the guardposts in is inefficient, you can switch the orders around until it is efficient. Settings like group move, attack move, or whether to focus fire on the guardpost before shooting at the defending ships when in range or not could be changed in place for each command.
You could prepare a 1/2 split of the command group and send half against one target and half against another, or other ratios. Each chain of orders for the subgroups would end with join the other half in their order chain, or continue with the command group chain.
You could easily assign more ships to a command group, or remove ships from a command group. For example if you are losing you could reassign the command group to a retreat command group that has orders for safe extraction of as many ships as possible.
If you need to do some changes to the plan in combat, you could normally grab a bunch of ships and give them move or attack orders without removing them from the command group, once finished with those temporary orders, or they are cancelled, they would join back up with the rest of the group. Of course you could break that group off from the command group entirely if you wanted to.
Form up points, such as wait for at least 80% of the command group before proceeding, or other thresholds, and triggers like wait for the AI Eye to be destroyed before proceeding, could provide even more strategic options.
I think that this would be a great addition to the game reducing micromanagement and giving a more strategic feel.
