There is some reason to see the revolution as reaching a climax in 1914-18. The new technology emarging now might be closer to the emerging technologies of the Second Boer War and the Russo-Japanese War.

The pace of the emergence is much faster, comparable to the weapon development run by the SOE in WW2. There are two distinct "Ministry of Ungentlemanly Warfare" books and Giles Milton is better for that side.

That is likely my bias.
