Thanks guys, some interesting thoughts.
I haven't yet had much of a chance to work with the scenario editor, but I should be able to take some much needed R&R over the Christmas period.
That said, I can see how difficult it could be to recreate a surprise raid. Note that the Italians did know that the LRDG was approaching Barce on the day of the raid (they had been spotted by a recon aircraft); in spite of that they were still unprepared!
And I take it that the aircraft don't just sit lined up on the ground to be shot-up and bombed??
Now, if I could find some kind person to devise some 30 cwt, India pattern, Canadian built Chevrolet 1533x2s as modified for the LRDG...
