My apologies, they are not a long range squad they are a mid to close range squad that just also happens to be good at range. Thanks for clearing that up.
Very misplaced sarcasm. I said they are
somewhat decent at long range because of sheer volume of fire from having six models alone. But that is not their role and they are not very good at it, and should generally not be used that way. Obersoldaten Kar 98Ks are pretty good at close range too but that doesn't mean it's an all range squad either.
G43 Panzerfusiliers are not great, not terrible at long range with 11,6 DPS at 35 range, which is not much more than stock Grens and Volksgrenadiers have (around 9), and they will get outtraded by long range focussed squads easily. By comparison double Bren Infantry Sections have 22,5 DPS (maybe a bit less I'm not sure if these Bren stats are the new ones) at 35 range and LMG Grens have 15,7. Obersoldaten and LMG Paras have around 25,5.
For the record I don't like the way Relic has designed most weapon upgrades as no-brainers either, but we're stuck with that now. Panzerfusiliers however are still a close-mid and moving orientated squad that
can fight at long range if they have to, but it's far from their preferred engagement range.
