The Kremlin Report (クレムリン・レポート Kuremurin Repōto?, Доклад Кремль), also known as the Wall of Germs (細菌の壁 Wall of Germs?), is an airborne biological weapon developed in Russia for defensive purposes. It acts as a deterrent to invaders who intend to or have captured Russia's nuclear missile silos. When the Wall of Germs is used, the silos become inaccessible or the invaders become infected.
