So what do we have here:
This looks good Starfleet coming in to safe the day as the bigdam heroes.
So after 18Minutes the disstress call ceases. Garrett increases speed and prepares for hostilities. Good call you never know what has crawled out of the woodwork to turn everything to shit.
Over one hour after the first distress Signal was recieved you are getting close and detect heavy naval fire. Garret is right to go to Battlestations. Here she should have send out another report to HQ detailing the situations and timestamps of what happened including the likely orbital bombardment of the colony.
So GARRETT KNOWS THESE four unknows bombarded a neutral colony for more than 60 Minutes and her first instinct is to go there weapons off and hail them? I hope she was a Career woman that never procreated that much moronic stupidy should not continue.
She should have come in full speed and killed the first one from surprise. Then continued firing on the second one while ORDERING the remaining ones to get lost or be killed.
Edit: This attack is a clear violation of everything the Federation stands for. Including the hour long orbital bombardment of the colony. So yes there is absolute justification of coming in guns blazing. As the federation espouses high ideals standing by and not doing anything in the name of peace would not have worked either.
After her stupidy the enemy gets the first hits in. Instead of using her ships high power to charge them firing she turns, opening herself for a pursuit by a numerical superior foe.
What follows is a execution. She is not salvaging this monumental fuck up even with two kills. It is not enough to clear her from the stupidy she showed earlier.
Recommendation: Posthumous degrading Rachel Garrett to Commander, a posthumous black mark on her records and dishonorable discharge for wasting one of our brand new ships. Further we recomend a change in officers schooling to remove the chance that future captains make the same mistake.
