What's the Story of the African Army?

Percy Herbert is sent out to galvanise mobile force as it's known in 1938. Some of the bad habits that then go into 8th Army come from then when their radios work, but their radio net to the artillery doesn't work. So Hobart's advice is just push on. If you can't, if it takes the artillery all day to answer a quest for a shoot, you just ought to push on.
