The Military Defense Commission (MDC) was a weapons development and research organization created by the United European Defense in May, 1939. The primary goal of the MDC was in response to scarce intelligence on the existence of the Chimera. The MDC was led by Albert Einstein, in which his recruitment by the UED piqued the interest of many European scientists, who decided to stay on the continent instead to the United States.
The MDC was centered in Luxembourg and had continued to exist during the Chimeran War after the Fall of Europe, in which the Commission was located within the Maquis' Luxembourg fortress. Dr. Claude Bouchard, a member of the MDC, and his daughter Raine became close to a breakthrough in stalling the Chimeran conversion process by developing a virus that eradicate the Carrier strain, thus grounding Chimeran conversion centers to a halt.
