And from the other link I posted;
There is a persistent rumor that one BFC member, Reg Courlander, took part in the Battle of Berlin, and destroyed a Soviet tank. By this time, Roy Courlander was far behind Allied lines, and the movements of the other members of this unit are clearly known. The only person who can be proved to have seen combat in the uniform of the BFC was their translator "Bob" Rossler, who remained with the Nordland division when it went into battle in Berlin, to fight alongside the Volkssturm, Hitlerjugend, and the other mixed bag units defending the city.
Obviously I can't comment on whether this is correct, I wasn't there and haven't researched the BFC!
