Who says they do 27 vs infantry when it´s 14 in the sheet ? They only get a buff vs vehicles but not vs infantry. As you can clearly see here:
I'm very certain its 27. The attribute editor (which is where Cruzz's numbers come from I think) makes it confusing, but Vipper's patchnote reference is a solid source. Even just using guards you can tell that the ptrs is doing more damage than the mosins when it hits.
Though the eapon had low accuracy, the high damage made the RNG killing potential on the PTRS much harder to react to.
The guards PTRS has always been, and continues to be, effective as an AI weapon. But it is not the best and it has absolutely been far more powerful in previous patches.
Vipper's right, the PTRS used to be dog**** against infantry. Yes it could do 40 dmg, but its accuracy made that insanely rare. And not in like an occasional-type rare, like way worse than the chance of an m42AT gun to penetrate a KT rare.
Their long range acc. (as Vipper provided) was .03. I hope I don't need to explain that means a 3% chance of hitting models with target size 1, and many squads have target sizes much smaller than that. It's accuracy was later buffed, they become OP, and so the dmg was reduced.
All of that is by way of saying, Guards could use a looking at currently. I like the idea of specializing them more in one direction. Maybe make them cheaper, and then you can select 2 DPs OR 2 ptrs+AT grenade? 75 muni for either.
