>Early versions of the Scud missile engine used the same propellant as its V-2 progenitor, ethanol and liquid oxygen. However, after field reports of the liquid oxygen vaporizing and the ethanol "mysteriously" disappearing, the engine was redesigned to use UDMH and IRFNA. Both are stable on the battlefield, and "coincidentally" is unsafe for human consumption.

Earlier versions of the Scud missile was propelled by ethanol and liquid oxygen. It was believed that Soviet soldiers assigned to the missile were drinking the ethanol fuel. This issue along with challenges of maintaining cryogenic temperatures on the battlefield has motivated the Scud designers to redesign the missile to be propelled by toxic hypergolics.
