Were the Home Guard given effective training, or did this contribute to the image of 'Dad's Army' as well as the age of the volunteers? If they weren't, was that again because it wasn't considered a serious threat or was it lack of resources?

Is it likely that the home guard were just made light of to alleviate the frightening idea of land invasion?

How would I be able to learn about ... for lack of a better way of putting it, the intended comms strategy of the Home Guard? how was it represented to the population and did that change/develop from introduction onwards?

Where can I find out more about the Home Guard and it's actual relationship to the expectation of German invasion vs how it was portrayed by the public?

Currently the picture I have of it is as a morale-boosting community service in war time, not really an actual 'force'. This is obviously mostly from the tv show but that didn't start until the 1960s and is nostalgic.
