I welcome all.
I suggest developers to increase destructive force (kill) rocket artillery (Katyusha, Grad etc.).
The basis:
Tests BM-13 Katyusha
"During tests the important feature of volley shooting by rocket missiles has come to light: at simultaneous break of several shells on the limited area from different directions shock waves, which addition, that is encounter attacks operate, considerably increases destructive action of each shell."

As we see - at systems of a volley fire i.e. which devastate the stock of shells for some seconds - the destructive force of shells should be increased in comparison with usual artillery since it is proved on tests which were conducted even by development BM-13 Katyusha.
Yours faithfully.
