On January 17, 1991 a massive US-led coalition responded to Saddam Hussein invading Kuwait with an Iraqi army of almost one million troops. The US and allies responded with 750,000 troops for Operation Desert Storm. Hussein launched a Scud missile that struck a US base in Saudi Arabia, killing 28 soldiers. The Pentagon turned to Delta Force and the British Special Air Service. The US Joint Special Operations Command chose Scud missile hunting as one of the top priorities.
