This is not about whether IS are good at long range or not, nobody disputes that IS are quite good at long range. This is about whether or not they are infantry that synergize well with the assault ability, and the answer is they don't.
IS are vastly inferior on the move for two reasons. First they have severe on the move penalties compared to most other infantry-even other bolt action rifle infantry. Second, moving typically means you will not be in cover and certainly not green cover so infantry sections will end up taking a further DPS penalty due to being out of cover while moving. This is why they are very suboptimal units for an ability like assault.
Yes, they will punch well above their weight if the enemy lets you just sit in heavy cover with assault active, but I would hope you are at a matchmaking level where you see these kinds of opponents infrequently at most.
I'd also like to point out that in this case a unit beating another 1v1 is irrelevant. Just because volks lose to IS in a long range firefight does not mean IS are a more suitable unit for one of these abilities.
again why ? u cant sprint and shoot , if this ability had only 25% better accuracy then this discussion would be the same, u are arguing that increase in accuracy are better
IN GENRAL for okw in general because they have better troops, get that bias out please
now again IS have better dps ON THE MOVE at long range, cause they reduced the penalty on the move but they still retain better accuracy at long range even with stg volks (as they have worse dps at long range than normal kar 98), and the game has a lot of cover just passing near it give them the bonus as vipper explained, not heavy cover
what u are saying is that since volks and sturm have better dps at close range they are better but at the same time shock and cons are shit with FMR while having even better close dps
