Vol Boarding Party

The Vol boarders move out into the hallway, preparing to unleash a hail of gunfire on anyone who sticks their head out. The shock troopers trail behind, uninterested in ranged combat.
T.L.A. Mothership Crew

The Admiral and minigunner move to defend one of the two access points to the bridge.

The two crewmen and the railgun trooper take the other.
Command Module Overwatch:

All 5 computers are still deactivated. One of them is right next to the Vol (it's located on the white cylinder) and another is right next to the Admiral.
Neo-Prussian Fleet

They accelerate towards the Vol, but can't get in range.

Their fighters can, however. Their line of fire on the railgun frigate is blocked by the destroyer... but they seriously fuck it up, destroying a turret and removing two of its three HP with a lucky plasma bomb hit.
The Vol Fleet

The Vol charge towards the Neo-Prussians and get some of their own back, doing a point of damage to each of the two ships. The Vol railgun frigate has 3 heavy missiles remaining.
The T.L.A. Fleet

"Admiral, who can we trust here?"
"Those black ships fighting the black-and-red ones are Neo-Prussians. They're solidly anti-Immortal."
"All right then!"
The Archer-class frigate fires its rail gun on the Vol railgun frigate, doing a point of damage. It launches a torpedo as well. It has 3 remaining.

The other frigates move towards the Britannian ships.
The Britannian Fleet

They approach the T.L.A. fleet.

Only the Q-ship's missile weapons are in range. It fires a torpedo (which is actually just out of detonation range of the two T.L.A. ships) and a missile. The missile does a point of damage to the Gamma-class frigate. The Q-ship has 7 torpedoes and 15 missiles remaining.
The Scythian Empire

"Helmsman! Head for the Immortal ship, full throttle! Engineering, charge up the guns. Let's see what this ship can do."
The Scythian ship's guns are now charged; they can each fire twice next turn.
The Immortal Empire

"Pilot, get us close to that ship so I can shuttle over."
"Aye, milord."
(Heavyfishcannon sent orders right before I started to run the turn, so I went with those)
Overwatch:

Send in orders.
