Put money in bag. I will not ask second time. - Combat Engineer, while capturing another Swiss bank
During the Soviet attack on the city of Geneva, several Swiss Banks were captured by the Soviet Commander and Oleg Vodnik's combat engineers to fund their efforts. The engineers managed to "persuade" the bank managers (most likely at gunpoint) to share their wealths with the Soviet forces.
When General Krukov arrived to supervise the mission, he captured some of these banks for his own use.
Strangely, the front door to the bank is a vault door.
