The United States has a particular force goal proposal which is presently under consideration with the NATO authorities. This would enable it to modernize its own chemical stocks with binary munitions. I am aware of the point made by my hon. Friend about the serious extent to which the wearing of the nuclear, biological and chemical warfare kit degrades the operational effectiveness of forces. If one side can oblige the other to fight in such protective kit but not be so encumbered itself, it confers a major operational advantage on that side.
