Before the patch they were a glass cannon unit that could, if properly used for flanks inflict a lot of damage. More importantly your flanking opposed a serious threat to soviet snipers and they seemed a good unit to oppose maxim & sniper spam.
With the new patch, they feel rather weak now since their dps range got nerfed pretty badly:
Near range distance from 8 to 3
Mid range distance from 16 to 15
Far mid distance from 35 to 28
The decreased received accuracy modifier doesn't make up for that in my opinion.
Before the patch they were scaling bad into late game, after the patch, they scale even worse. I honestly don't see a reason for a double Stormpio build anymore, with the exception of certain maps like Stalingrad and Ettelbrück.
Update 10.09:
As Cruzz pointed out Soviet weapon teams are more durable now, due the removed Received Accuarcy modifer (25 %). Together with the Sturmpio damage nerf, this is a double Nerf.
Personal Note: I find it funny that Assault Engineers with M3 Grease Guns now outperform Sturmpios (elite troops lol) with their Stg 44.
Assault Engineer M3
Range distance near from 8 to 10
Range distance mid from 14 to 18
Maybe the Stg 44 'range distance near' nerf was a typo in Relic Quality Management Process? I mean 9 and 3 look alike. I know this game is not about realism, but grease guns better than STG 44? That breaks immersion since they have the same squad size.

Here you have his opinion about the Stormpioneer issue.
Furthermore our beloved Senior-Strategist Milkacow made a very informative post about units and their effective ranges, clearyfing confusions Players like me might have.
Read here and here for more information.
TensaiOni made a tool that lets you compare the damage output of squads.
You can find it here.
When I'm back home (around Friday) I gonna upload some videos which standard combat situations between Sturmpios and allies core infantry.
