320mm rocket carrying pioneers

[Weasel]

Aren't there plenty of pioneer units in the OOB that use already some form of demolition charge?

I went through the German OOB, this is how many have demolition charges = 0. I did find that they carried numerous different charges for demolitions and such, but not one sight stated they carried 200lb rockets. They also carried two types of flame throwers, a regular type 41 and another that only gave a 10 second burst, but I don't see it in the OOB.
