I believe you Liz: of course they wouldn't send the third in line to the throne onto the front line. We never know what the Queen insists or even thinks. Perhaps they'll sent out a look alike: I wonder does James Hewitt have any more sons?
He's not a Commander - there's isn't such a rank in the British Army. He's a second lieutenant or corner if, like me, you can't spell it.
His name is (or should be) Saxe-Coburg-Gotha. Hence his fancy dress choice.
Troops home asap please!
