“The photos are promotional images for yet-to-be-released merchandise for The Last Jedi.”
A Red First Order Guard:
(Some recently leaked photos of Lego sets suggested that Snoke might make a proper appearance in TLJ. These guys might be his equivalent of Palpatine’s Royal Guards.)
First Order Stormtrooper Officer:
First Order AT-M6 (our first proper look at the so called “gorilla AT-ATs”):
I can’t be more tired of all the design clichès of this generation. The assymetry in the armor (Kanan, Rey, Anakin’s scar, the iTrooper from TFA), the roman centurion (Saruman’s Uruk-Hai in LOTR, the Lannisters personal guards in GoT, now the “pretorian” guards in TLJ).
Just have a fantasy universe anywhere these days and make a safe bet that some designs will be recurring over and over again.
