Tripartite arrangements were completed in December 1949 for collaboration in military standardization among the armed forces of Britain, the United States and Canada, as a step toward fulfillment of the provisions of the North Atlantic Military Production and Supply Board. Under these arrangements, which were similar to those made by the Brussels Treaty Powers, the three countries would pool information on almost every kind of conventional weapon used by their fighting forces and would study together such advanced weapons as guided missiles. “These arrangements will insure that in time of necessity there will be no material or technical obstacles to full cooperation among the armed forces concerned and the greatest possible economy in the use of combined resources and effort will be obtained,” the announcement stated. Military liaison committees had already begun work on the first phases of the exchange.
