Wasn't this Katyusha the one who could use such thing?
We do not use this one nor intend to do

About the suggestion, I'm not sure the "sledgehammer" fits CoH or Soviets at all, let alone we already have a couple of artillery emplacements in that tree. It seems to be a huge weapon, and once we add it everyone and their dog will complain about why we are not adding the Karl-Gerät for Germans or any other heavy artillery unit. This unit seems suitable for campaign but not to multiplayer.
