Why are space marines such a popular science-fiction trope
Naval aspect perhaps?
Marines are deployed from ships (well, sort of..) and space is generally analogized to the oceans. Space exploration, combat, etc.. is analogized to Naval exploration, combat, etc.. Perhaps theres also a percieved cultural elitism aspect? Space Marines > Marines > Army > etc..
If anything, maybe this shows the weakness of our creativity?
"Paratrooper" isnt exactly a creative name, but its accurate to level. So was Marine. Space Marine is just us being to intellectually lazy to come up with a new name.
and what if any theory supports their development and deployment?
Probably the same one that supported the development and deployment of marines.
Also why are they so awesome?
Because Space/Astral grunt sounds odd while Space Army acronym SA has an uncomfortable conutation with the Brownshirts. Also, "Space Marine(s)" rolls off the tongue better. Would you rather Star Soldiers? Cosmic infantry? Space trooper?
Jaded centrist. Wary Cautious liberal. Obligated Engineer(Civil).
