What is reported to be Russian barrier troops executing fleeing soldiers. Wait. I thought fleeing enemy was still considered combatants?

Showing my age here. Obviously sensibilities have changed but I was taught that fleeing enemies were still combatants and were to be treated as such. I won't even go into "cleaning" or "tidying up" a battlefield. That's one good thing (probably the only good thing) about this war. If people are paying attention (which I doubt) then they'll quickly move past the "glorious" warfare insanity that some appear to have.

I can't help but think about those Jokers that have been "lucky" enough to have survived the fight so far on both sides.

Everyone says the winter wasn't bad in Europe?  It was for the guys in the field.  That you're getting less rain?  They've been pissed on.  The summer?  Ate up by bugs, boiling in their clothes and probably not enough water to keep themselves hydrated.

And if they remain lucky they get to do it all over again for the following year.

Back on task.

Shooting a fleeing enemy is legal right?
