Where the Brazilian forces equipped completely by the Americans or did they have their own equipment?
Brazil and the United States signed a political-military agreement between the two countries on 23 May 1942, prior to the Brazilian declaration of war against the Axis powers. This agreement already established the employment of Brazilian troops in war operations outside the continent. The agreement also promised all United States support to the Brazilian coastline defense, as well as United States aid in arming and equipping the Brazilian Expeditionary Force (BEF) before and during the war. Brazil, on the other hand, would provide several supplies to the United States war effort.
Detailed below is a transcription of a few articles in the agreement which most enhanced the American cooperation:
