(b) Ginsu (proper name; etymology) https://en.oxforddictionaries.com/definition/ginsu
(c) For R9X to work, the missile must land about within a yard from the target *my guess, depending on long the blades are). Can the GPS accomplish this?
----------------------added on May 11
Yesterday afternoon I gave more thought about R9X missile. It is impossible that GPS (not precise enough) alone guide the missile. Looking at the wreckage of the two cars where the targets sat in, I realized they were moving targets (not suitable for GPS), which must have been guided by laser.
