The Marines tried to use this missile for close support

The Marines have always tried to ensure that the grunts on the ground get reliable support from other assets, whether that asset is naval gunfire, artillery, or aircraft. Historically, they've been willing to consider solutions that might seem completely outside the box in order to get the grunts the support they need to survive — and win — a firefight.

In the earlier years of the Cold War, the Marines turned to a ballistic missile for close support — the MGM-18 Lacrosse. This missile was to supplement artillery by taking out specific targets on the battlefield.

To get this missile into the theatre of operations, the Marines developed a mobile ballistic missile that could be mounted on the back of a truck. The Lacrosse had a range of 12 miles and could be armed with a selection of warheads — either a 540-pound shaped charge or a W40 nuclear warhead. Regardless, whatever this missile hit was sure to feel it.

The United States Army was intrigued by the MGM-18 and quickly took over the program — though the Marines stayed involved. The Lacrosse was guided by forward observers using radio control. Not bad for the late 1950s, but it was very cumbersome, and if the signals were jammed, it could put friendly troops at risk.

The MGM-18 Lacrosse was decades ahead of its time. Ultimately, the Marines decided not to buy the system, but the Army put it to work from 1959 to 1964. Today, sophisticated evolutions of this concept are still used. Troops can designate targets for laser-guided missiles, like the AGM-114 Hellfire, and artillery rounds, like the Copperhead. They also have weapons like the BGM-71 TOW missile and the FGM-148 Javelin. The Lacrosse may not have been the right solution at the time, but today, the idea behind it is going strong.
