Heh, my Grandfather was an Artillery spotter during the run into France, spent most of his time operating several miles ahead of the Allied lines with a radio on his back that was bigger and heavier than a modern backpack.
He told me a story once, he was hiding out in a Barn when he suddenly heard a sound behind him, it was a German soldier, remember, with this pack on his back there wasn't a hope in hell of him getting to his gun.
My Grandad and this soldier just stared at each other for a couple of seconds before the German soldier said, 'If Adolf wants it, he can do it.', and threw down his gun and surrendered.
That story always sticks with me, even though Grandads' dead, because I wouldn't be alive had that soldier acted differently.
