I'm working on building equipment and aircraft of the Korean War. I've been researching it and reading a few books. Two things have appeared quite a few times, and they've got me puzzled.
In both "The Coldest Winter" and "The Final Crucible" the authors mention (and eyewitness anecdotal evidence states) that the USA and the USMC used "rockets" and "armored personnel carriers."
What type of equipment is this? Are the rocket launchers the Sherman Calliopes? Are they something like a Nebelwerfer? And what is being referred to by armored personnel carriers? Is this in reference to halftracks, amtracs like the LVT-1, or something entirely different?
Thanks for any and all help!
