I recall an 82nd Airborne experiment of the late 1970s known as Slammer VI, essentially the mounting of six rocket pods from attack helicopters onto an M151A1 Jeep. The idea was to offer the airborne something with a capability beyond that of their 81mm mortars, if not that of a 155 SP battery, thereby freeing up the Airborne's helo-delivered 105mm Light Guns- or for those instances when they weren't available via helo delivery, or were needed for direct fire missions.
The Artillery folks at Ft Sill found out about it and were horrified: with 17-pound warheads, the setup put more steel on target than either the 81mm or 105 could deliver, nearly equalling the cannon's capability, and not only cheapbeyond belief, but using assets already organic to the airborne and light divisions. It became a threatr to the careers of those pushing the then-yet-untried MLRS system, and so was killed by orders from on high.
But now, there are terminal guidance warhead systems like the Army APKWS available for the HYDRA-70/2.75 inch rocket, a sort of *poor man's Hellfire*....And if it works off an Apache helo, it ought to work off a Jeep or Humvee....
