320mm rocket carrying pioneers

[Weasel]

I am reading a book called "In the fire of the eastern front" by Hendrick C. Verton who was a Dutch volunteer in the Viking Div, and on page 52 he writes: "This Division was one of the armoured divisions, equipped with rocket-launchers and machine gun squads and we bore the burden of those machines. We had to carry them, which we did...."

Now you could read this two ways, 1. that they carried them physically into battle as per the OOB, or 2. being armoured they were carried on vehicles (machines). I still lean towards 2.
