text_A: Hall volunteered for the United States Navy when World War II broke out, serving as a machinist in Guam. During the first years of the war in Europe, the CPUSA held an isolationist stance, as the Soviet Union and Nazi Germany were cooperating based on the Molotov–Ribbentrop Pact. When Hitler broke the treaty by invading the USSR in June 1941, the CPUSA began to officially support the war effort. During a brief leave of absence from his naval service, Hall was inducted into the National Committee of the CPUSA. He was honorably discharged from the Navy on March 6, 1946.
text_B: Did the circumstances of Hall's election mean that he could have died in combat prior to first taking his (literal) seat in the committee's offices?
NO.
