C5.2 - Bounding fire from inside a building

[Maurizizio]

Dear all,
need your support again. A tank is using bounding fire from inside a factory. Looking at the DRM - C5 - looking at C5.2 it looks like the tank is using Case B as +3 instead of +2, is this correct? Thanks

C5.3 says : "it must add the +2 DRM of Case B to the applicable Gun Type DRM of Case C"... Which creates a tension with Case B explained in C5.2, which indeed states that the DRM is +3 from woods/building/rubble...
Good question !
