Despite some initial interest in using the captured B1 Bis turretless for the role of an assault gun, it was simply not adopted.
Records state that they were instead sent for testing out as ammunition carriers, as firing range targets and presumably some parts scrapped or salvaged. Only 20 B1 Bis and single B1 Ter (36 tonne prototype) tanks were seized by the Italian military in
Marseilles in 1940.
