Also, the backstory for how we ended up at this particular point is in itself pretty complicated.
Suffice it to say, due to a Social Admiral's false bravado, a lack of understanding of either side's protocols or combat practices, and one teensy ambush, the militia won't assemble its full force in one spot for fear that the WarShip in orbit will shell them into oblivion. The Star Colonel offered to remove his warship from orbit for the trial, but the Militia's not willing to take that chance, which is why they sent such a small force, and why they didn't hand out info on what they would be using in advance.
The Star Colonel, also fearing a trap, brought most of his cluster, but true to his word, ordered the warship back to the jump point.
And here we are.
