Thanks for you guys help.And here are the screenshots of the article
Make sure to read them before you posting any comments. There are at least four more parts coming up for this test. I'll finish uploading by next Friday.
There are a few issues with the targets for your tests as Volksgrenadiers aren't exactly the target axis artillery should be firing at, better might be a mix of some teamweapons and mostly baseline infantry force (maybe damaged or down a model) consisting of grenadiers and volksgrenadiers - this will lead to different kills per barrage but shouldn'T really matter as it is mostly about the percentage of units that can survive.
The Calliope could make a nice addition, although it is even more expensive then the stuka and doctrinal.
It might be useful to know the exact positioning of those units and i hope you did use similar firing ranges as yellow cover usually makes units clump more and terrain differences migth lead to different outcomes in the results.
It migth also be worth noting that the Katyusha (or most allied arty pieces for that case) will deny areas for a certain time, while the axis counterpieces only do alpha damage.
Another weak spot for the Pwerfer compared to the Katyusha is the shorter max range and later accessibility (the stuka has the earliest but that is somewhat balanced as the price is pretty high and it delays further tech quite a bit).
The testers (Noobs vs Pros) are troublesome, as the game should be balanced at a high level otherwise tourneys would get onesided and migth be won or lost by a cointoss, not skill.
