NA to WP CH though - per Q&A:
A24.31 & C11.4
C11.4 ends with “A CH automatically destroys both the Gun and its manning Infantry.” and A24.31 defines CH possibilities for
WP OBA, Ordnance and grenades. Can a WP CH destroy a gun per C11.4 from OBA? Ordnance? Infantry Grenades? Or does the
earlier part of C11.4 which requires an IFT roll preclude any form of CH w/WP from automatically destroying a gun?
A. WP cannot destroy a Gun.
If it was emplaced/entrenched, on a CH the TEM would be reversed, so +2 as you say unless OBA against entrenched (or something different if in a Cave). A gunshield is not a modifier that applies to the WP NMC, either normally or on a CH.Probably with a +2 DRM for being emplaced? (or perhaps for the Gunshield?)
