Seriously, I'm a bit older than he was then. It'd be possible to hide him in 'Camp' but he could only broadcast recorded messages from use-once transmitters. Modern radiolocation's a bit better than the Nazis in the 1940s. Could get him evacuated by an SBS unit brought in by submarine, I suppose.
Yep, the officers who led the attack specifically state those were their orders.
Otherwise it depends where you're transmitting to - omni, if you're covering all of 'Camp'. Good earthing conditions, though...
