This might be my favourite way to interperet the theme (of what I've seen). In terms of execution, I like the visuals and atmosphere. The main mechanic brings interesting tension as I keep wondering what my soldiers will do.
I often tell the soldiers to hold fire when we have to cross a crowded area, only for them to stand around until it expires and cause a massacre! Could be something I just haven't understood about the mechanics, or maybe there's something missing there. Some way to manage their positioning and facing maybe.
