Recently I have come across many assertions about “military-grade” novichok nerve agents (though not in New Scientist). These leave me wondering what other grades there are – domestic grade?
The editor writes:
• We suspect that, beyond adding spice to copy, the term is meant to distinguish “military” from “paramilitary” grade, the presumably inferior product of a non-state actor.
