What?
Does the shrek upgrade reduce the AI value of the 3 other models who don't get the shrek?
Because 3 shrek upgraded squads is still 9 pfusiliers with k98s; putting aside the 6 shrek shots, are you telling me 5-riflemen or 6-conscripts can beat 9 pfusiliers?
I will gladly put this to the test when I get home, but it sounds very PressXtoDoubt.jpg.
Panzerfusiliers Kar 98K have pretty poor DPS (especially close to mid range) and because the Schrecks will always occupy the final two weapons, Allied squad would only need to kill 3 models to render a Pfussies useless, as opposed to Pfussies having to kill 4-5 models to force a retreat.
One stock Riflemen has ~21,88 DPS at range 10, which is the same DPS as 7x Panzerfusiliers Kar 98K. So they will be able to easily hold their ground against at least two charging Schrecked Panzerfusilier squads, and possible a third if they get some nice RNG and favorable positioning. That's why I said up to (and not including) three squads.
One 2x BAR Riflemen has ~28.53 DPS at range 10, which is the same DPS as 9x Panzerfusiliers Kar 98K. So they will be able to hold their ground against three charging Schrecked Panzerfusilier squads and might even win charging into them instead.
Cons could win against two Schrecked Panzerfusilier squads, because they have basically the same DPS (whoever charges would lose, but it's still a cost effectiveness win for Cons either way). Penals are a bit better than stock Riflemen.
Anyways the point wasn't what exactly can and can not beat a certain number of squads, the point was to illustrate Panzerfusilier AI dps after their Panzerschreck upgrade gets really, really poor. And it's nothing compared to the AI DPS that the old Volksgrenadiers with Panzerschrecks had.
I watched Momo4sho's replay and his OKW teammate's Schrecked Panzerfusiliers got a grand total of I think 5 infantry kills in about 20 minutes of running around with Schrecks and continiously running into enemy infantry.
