I have no idea if this "Sebastian" is a reliable source, but I pulled this one off the same moscow news forum on which the, so far. reliable "Sergei Roy" has reported. Possibly describing Soviet-developed Novichok-33 [*newcomer*] binary nerve gas, or possibly a derivitive, which they've also studied as to its properties when delivered in very small, controlled doses over longer periods of time than are expected under battlefield usage.
Interesting stuff...
What an interesting link. Is the reason I can't access the "main page" that it is a Canadian source? Anyway, thanks....
