So, thanks to Virr's gif (demo would be sweet too, but this gif is more than enough to justify the ban) it's blatant that you clearly don't understand that you have to give Ts a chance to, you know, do your orders. This is all an assumption, but my guess is that you were ordering Ts to unstack while being fired upon; in which case you gave them like, 3 seconds during the whole commotion before opening fire on the collective bunch of them.
I won't throw a vouch in here, though I will say that I'm leaning toward a negative one given the context here. While we don't exactly have a time set in stone as to how long a T has until they are considered a rebel via not following orders, 3 seconds (assumption) really isn't enough time, especially provided the whole commotion going on. There are a bunch of variables that will influence this, but being shot at and panicking when giving orders shouldn't enable you to kill a whole bunch of them within such a short time frame.
Just to clarify, the majority of this post involves assumptions, hence the lack of a vouch.
