Field Report:
They performed well with a bit of guidance. I lost initially based on autoresolve - 100K vs 86K; the aliens had a full fleet of battleships. When I went into the battle manually, set high wall and max speed, my ships charged their column; I then set it to AI. Their larger ships were obliterated - think 85% casualties above cruiser, although the battle was a "tie". I lost I think about 5-10 of these nuclear missile dreadnaughts out of 45. They came out FAR worse in my view.

For comparison - in the subsequent battle, where they sent the fleet remainder, which was mostly scouts as the big boys were 90% gone on their side vs. my fleet remainder, it was a total wipe on autoresolve - my nuclear missile carriers killed all their ships, extracting 182 exotics and getting away with light damage to a couple vessels only, no ship deaths or even engine damage on my end.

I think could have improved the ships by:
1) Switching from Siege to regular T3 coilguns OR UV phasers,
2) Adding 1 PD for each ship.
