There is little comparison between the Brumbar and Scott also.
In addition Ostheer as faction have little to do with USF when it comes to design faction. Comparison between the Wefer and and Pack howitzer are simply misleading.
And the US has nothing like the werfer stock, so they get things like the pak howy instead. They don't have abrumbarr so they get the Scott.
You've misled yourself if your reading that as a comparison. I'm literally commenting on the fact that the factions are completely different. Hence the clearly sarcastic suggestion about making the calliope stock...
They arent similar units but they are the closest units to each other on the respective stock rosters is all im saying
