Personally, I don't like the crossover to hobby/amateur rocketry. It's one thing to build models of missiles. It's quite another, in the eyes of an uninformed public, to have a tangible link between an actual weapon system and amateur rocketry. To those who (incorrectly) assume all rockets are just dangerous missiles in disguise, this might 'confirm' their fears.

Yes, the old "Smokey SAM" motors from Vulcan Industries were used to simulate surface-to-air missiles for the Air Force. But they were mostly for the visual effect (for the pilots) of seeing something shoot off the ground. They didn't really look like missiles and they certainly weren't guided. Now, a guided missile boosted by, what, a cluster of "I" motors?! Ah well. Credit to Raytheon for minimizing costs!
