The PE Kar98 is almost identical to the gren and volk ones. The Volk does 10 damage, the PG does 12, and the gren does 15. Other than that, in terms of accuracy, ROF, and all that other BS, they are the same. In conclusion, use them like volks or grens, keep them at long range vs other infantry.
Edit: Ah, Shit, forgot I just made a new profile, this was Leafedge. Sorry for breaking the smurf rule.
This is incorrect. The PG K98 is about the same at close range and significantly worse at long range, A squad of 4 PGs with K98s has identical dps as a riflesquad at long range, and identical dps as a volk squad at short range.
In otherwords, its just crap. Its not good at long range, its not good at close range.
