From War on the Rocks:

The historian David Edgerton authored a book entitled The Shock of the Old in which he argues that our society’s collective obsession with rapidly changing technology often blinds us to the older tools and techniques that actually drive most of what we observe around us. We believe this logic can be applied here. The diffusion of 100-year old combat techniques, coupled with readily available technology, may create serious threats that are not currently being considered.
