I agree with you, but I have to take a moment to point out that the Il-2 bombing run does exactly the same thing. At least I'm pretty damn sure that it does.
Very true IL-2 bombing run will achieve the same thing, however in the grand scheme of things the IL-2 bombing run is seldom used and far less attractive for a number of reasons:
- IL-2 costs more at 200 muni compared to SDB which is 160 muni.
- IL-2 has red smoke makers whilst the SDB has only a audio warning (which can be mistaken for a shot down plane until its too late).
- IL-2 has a higher damage potential but much lower effective kill radius compared to the ninja buffed SDB which has just massive. Combined with lack of red smoke makes the SDB good at punishing blobs and wiping out support weapons wholesale. IL-2 is only really effective against a station target like arty or PAK-43.
- More importantly the doctrines that have the SDB all have the reacon plane as well, meaning the arty positions can always be revealed. Only one of the Sov commanders have both the reacon and bombing run, meaning IL-2 has less opportunity to counter the axis heavy supports.
It might also be worth pointing out that in days long past, the go to counter for Soviets was the BM-14 / ML-20 / B4 precision strike. It has since been removed, leaving sovs with fewer options for counter arty. And that’s just the soviets, other allies factions have to turn to less conventional counters.
Bottom line is that allies have less of an easy time to counter axis heavy support weapons.
I do find it very odd that these one-click, instant counters to fixed weapons which have no counter play whats so ever, exist in the first place - really does go against the very core of the game.
Edit: forgot to mention that IL-2 bombing run is also particulary useful against OKW FHQs - when they can be spotted.
