Ackerman's helicopter is an aircraft used to transport the President to safety in case of danger.
The helicopter is featured in Operation: A Monument To Madness. It was used to airlift President Ackerman after his plan to level Moscow was thwarted by an Allied Commander. It was shot down by the Allied forces, killing the mad president.
It bears a resemblance to the real life Emergency Escape Helicopter for the President of the United States, known by its callsign, Marine One, when carrying the President.
