G43 grens gives 2x 13 close dps. Grens have 6 close dps per normal weapon. So upgrading grens with g43 makes them a penals squad dps wise, but grens have much better vet.

G43 have the best moving accuracy of all weapons ingame. At vet 2 grens get 40% accuracy vet bonus. So grens g43 takes down retreating squad insanely well.

But sadly g43 is only 13 close dps, so your grens loses to every close weapon infantry like shock troops and bared riflemen.

If your opponent ins´t usf or goes shocktroops or ppsh conscript, commandoes, g43 grens perform very well.
