I disagree with the sergeant on the matter of taking time, it's fine to take your time investigating and such before the fight, but once the fight is on, you want the opponent on their backfoot. Shadow Stalker would have won if her aim was better or if she decided to shoot again immediately. If she had waited, Zapp (Their name is ZAP) would have zapped her anyway and that would have been bad news. If she knew this based on there name, then the best plan was exactly what she did, shoot first.
The Lesson there is to prepare for things to go wrong and to make plans to deal with explicit weaknesses, such as lightning. Or even accept that there will always be someone out there with your kryptonite or just straight up stronger then you.
While Shadow Stalker did ignore him saying they were more then just Projections and their more human qualities, in a world where AI is a thing, where there are social Thinkers that can convince you of anything and tons of crazy people, is it that odd to think the "More then just a projection" thing was just a cape getting attached to their Projections or Tinker creations? Hell, one of them died and came back, she would certainly not think them any less disposable after that. Shadow Stalker might even argue that he should get used to seeing this as his chosen profession is Dangerous and his summons Will be in the frontline. I'm not saying her rudeness or demeanor are good or acceptable but I am saying there is a understandable logic to her actions.
Still a Rude Bitch though
