man they don't even fire the tiger ii...
They had to have. That had to have been the initial salvo, maybe with KE or APFSDS or the like. Even locating / direction finding small arms fire at that distance is near impossible. You'd hear a supersonic crack as it whizzed past, maybe, if not even that and only a small "thud" if it was a small caliber that fell transonic.
Context: Having stood downrange marking targets in a scoring trench at 200-600yds while being shot over.
There is no way to even remotely reliably hit something at 2,000 meters, two kilometers -- 2,200 yards -- without anything short of an accurized 300 Norma Mag or starting to creep into larger calibers like 338 or 416. And that's assuming a spotter, perfect holds, prone, wind holds (maybe doesn't exist in dungeon), etc.
Absolutely unlikely with a WW1 bolt action or Rem 700 pictured here, unless that Foreigner had superhuman abilities and magical ammunition. At which point it should no longer even be considered a "gun", instead could be thematically replaced with a magical staff or sci-fi laser beams. But author
chose to use something relatable, without doing background research.
...or maybe it was a translation typo, and instead was "200 meters" (220 yards). One kanji different: (sen) instead of (hyaku). Then running and evading becomes a lot more beleiveable.
