Actually the American army refers to the Infantry as the Queen of Battle and Artillery is as the King of Battle. There is a marching cadence in which you can see the reference. One version of it can be seen at the following link; but you can actually hear it on youtube as well.

As far as the drumfire rules.... haven't had a chance to employ them in any WWII scenarios. It would make sense though, since one use of artillery is for interdiction.
