i think that’s the plot of Tenet (2020)

round pizza makes logistics inefficient

there were reports of NK combat engineers to be deployed in russian rear areas, Perun mentions this in last video https://www.youtube.com/watch?v=FTXwmcIfY0Y

that flag was irl dropped by a drone

there were rumors of nk soldiers being sent to russia soon, but no solid proof yet

it’s a few days old, probably not the most recent by now

might be relevant: i don’t think these three were equals. first and third one are kitted out, but the second one (targeted) had no weapon, no backpack, and sneakers as shoes. russians consider some categories of soldiers as expendable, maybe he was from penal unit or something like that
