Is this "Kampfzange" (claw) on the Luther or Loth supposed to be range C or range 1. I know it says range 1, but so does the "Knife & Grenade" on one of my infantry. Was the claw supposed to be change to range C when they introduced range C?

Nope, the old Knife and Knife & Grenade were changed to range C, but the Kampfzange remains range 1.

This came up in regionals and they played it as a C weapon. I was pretty sure it was range 1 still. The card update didnt change the range value.

There is no doubt that it's Range 1, not C. The updated cards didn't change it, and FFG has officially answered it's still range 1.

It's a C weapon in Dust Warfare… perhaps someone was confusing the two games?
