Spoiler: I didn't realize we were talking about soldiers when I wrote what's inside of this. Woops. :l
I was being sarcastic, but at the same time, I was talking about lower ranked units. i.e. 05/i5/Ui5
Because I highly doubt anyone that just got a uniform, unless mentally/psychotically fucked, would be able to just blow a little girl's brains out without second thought.
Also, higher ranked officers should act as the old man. Lower ranked units as the two soldiers defending the girl. Because when you're a low-ranked unit, you're more investigative, than anything. Almost as if you were a defense attorney, or something. Unless it was something that went against your morals.
Something that doesn't, i.e. executing a man for propaganda, would probably make you think your own morals/self over.
EDIT:
But I also have two opinions, that literally contradict each other.
I hate hardass 05's, unless the canon says that they were totally brainwashed from day 1 and are now Combine. Chances are, as a civilian, you would NOT know what rank the units were, nor would you know the system. Unless they wore rank armbands, which would be extremely fucking retarded, as that's just as bad as saluting in public, if not worse.
I also like hardass 05's, or something higher ranked that's beyond hardass, that doesn't question orders. How they act completely blinded by the Advisors/Breens lies, are are TOTALLY pro-union. But then at the same time, that does not justify killing someone young i.e. 17-18 years old without mental repercussions. 05's should act a lot like the two SS-Schutze, or Riflemen (first two soldiers), and a LITTLE like the SS-Untersturmfuhrer, or Lieutenant (third soldier, or guy speaking to the old soldier, the SS-Sturmbannfuhrer, or Major.)
Bottom line is:
If you're going to act hard-ass, don't take shit. You were ICly brainwashed as a citizen to go pro-union, and you were even more heavily brainwashed while in the Union. You were then augmented, and brainwashed some more.
And if you're going to be a hard-ass, and full pro-union, do it right. Don't go lol-rogue because you got bitch-slapped for feeding a Vortigaunt when you weren't supposed to.
Don't be that psycho bitch rogue unit with dual katanas, blonde hair down to her ass, and fuck everyone. Because no.
Just no.
That's really not cool.
And try not to be edgy as fuck when you're being a hard-ass, although that may be difficult.
Like I said, my opinions completely contradict each other. :v
Depends on the canon.
Because if you were a Citizen under the UU for 16 years or more, despite having family members/friends killed, you are brainwashed. You've been fed lies since day one. At first, you believed, "Ha! Bullshit!" But then the Union began to prove their lies. Because if you tell a lie often enough, it becomes truth political truth. Then political truth becomes truth through a simple lie. Then you can find the loophole, implying you wake up from the lies, and reverse what you've been told since day one.
idk
im ranting, i could probably make a better post about this later on
but again, its hard to type while in the ceiling
especially laying down lol holyshit.
Spoiler: This is my response when I figured out that I was supposed to be talking about Combine soldiers. Fucking derp. >:v
EDIT 2:
I just realized that we were talking about Combine Soldiers and not units, fucking penises.
Uh, soldiers, they should actually act like the Major in that video clip, tbh. I mean, in that way, they're not completely robotic in how they fulfill/follow orders.
