On 21 March 1962, the minutes of the 200th meeting of the Council of Western European Union set out the discussions on written question 51 of the Assembly. British representative Sir Evelyn Shuckburgh says in his proposed reply that the importance of standardising small weapons and their ammunition is well understood. Moreover, the Armaments Committee of the North Atlantic Treaty Organisation (NATO) has recently set up a working group to review national requirements for 20 mm weapons and the standardisation or operational interchangeability of their ammunition. It is agreed that the Council’s draft reply to the WEU Assembly will only be sent after it has secured the agreement of NATO.
