FG42
Beating a dead horse but, this is correct. As every post in the thread has mentioned: They have the FG 42.
To break it down, every weapon is good at something. For the purposes of this list, okay is equal to a typical bolt-action rifle, bad = worse than bolt, good = twice the dps of bolt, great = triple dps or higher.
- Bolt action rifles being the standard, are okay at every range.
- LMG's are okay at close range, good at mid range, and great at long range.
- SMG's are great at close range, okay at mid-range, and bad at long range.
- SAR's are good at close range, okay at mid-range, and okay at long range.
- Assault Rifles are great at close range, good at mid-range, okay at long range.
- The FG-42 is great at close range, great at mid-range, and great at long range!
The FG-42 is the only weapon that excels at every range across the board. Up close it matches a Submachine Gun, at long range it matches a Light Machine Gun, and at mid-range it is unrivaled by any typical weapon except Obersoldaten MG 34; but that's 1 LMG vs 4 FG 42's.
Edit: Obersoldaten StG also matches it's mid-range DPS.
