Gent's, having raised many a F34 to write-off MT vehicles damaged beyond repair, ISTR that an insurance company did act on behalf of MOD only if there was a third party claim in that particular incident (it may have been General Accident, but I stand to be corrected). If there was no third party interest, then MOD took the hit. The write-off was, in any event, classed as a stores loss and set against the appropriate category - i.e. culpable/non-culpable.
