Borrowed? Heh. Nicked whole-cloth, more like: General Hux, addressing troops arranged in the “Nuremberg” pattern; the battle of Mimban = WWI Western front, in space; stormtroopers in Stirnpanzer; Soontir Fel = Red Baron — to say nothing of Baron Valen Rudor, and Vault Skerris; etc.
Hell, if you’d like a fun rabbit hole, look into the Twi’leks’ Ryloth liberation as French Revolution, OG Sith as ancient Egypt/Aztec civs, Empire expansionism as HRE/Spain/US, etc. 🤓
The man’s not known for ingenuity. Then again, neither is GRRM. 🤷🏽♂️
