The weapons seem to have a kill count limit, as in some playthroughs, switching to another required weapon will allow the count to rise.
NCR reputation will remain the same as long as kills are performed in sneak mode.
Sgt. Kilborn, Sergeant McGee, and Tech. Sergeant Reyes are not included in this challenge, as they are only non-commissioned officers. This goes for all sergeants.
This challenge is not repeatable.
