The US Rocket Boys look a lot like Bob Murchs Rocket Trooper...
Considering that they have the same sort of reference material this shouldn't really be surprising. Besides, this figure has a flight mask and not a Rocketeer style helmet. And if it follows the concept art there are flight fins on the rocket pack that are different as well.
I quite like the range. I wish they were more in scale with the "28mm" scale figs from Artizan and Pulp Figures but they are really good sculpts.
I would prefer a few single piece figs from them but the multi-part minis they have allow you to repose the figures giving you a lot more options from the figs. They also typically ship with multiple heads and arms so even troop packs end up with a fair amount of variety from them.
