I haven’t seen Rogue One as of this writing, but I’ve seen the trailers.
Can we talk about Death Troopers?
These are a variant on the black-clad ‘elite’ stormtroopers or Shadow Troopers that sprang from the EU in its Legends days and gradually grew in popularity among the 501st cosplayers at conventions, and are now about to charge full blown into Star Wars canon onscreen.
Yeah, they look really cool.

I’ll buy the toy for my son ’cause he likes ’em, but even Death Troopers play with the classics.
But I’m not a fan….AND I’LL TELL YA WHY!
Stormtroopers are about shock and awe. They wear this pristine white armor not because it’s practical, but because there’s something incongruous to their appearance when they kick in your door or come hut hut hutting out of a dropship.
I remember the first time I saw them blasting their way onto the Tantive IV in A New Hope. Their appearance made my brain misfire. In my kid’s mind, bad guys wore black (Zorro notwithstanding, but he was sort of pretending to be a bad guy). Soldiers are gruff, down and dirty, but stormtroopers are spotless, unblemished, and regimental. There’s something in that that gives the mind pause (and in that pause is where Stormtroopers shine).
Stormtroopers represent the Imperial notion of Order with a capital O. They’re not interested in practicality, they’re there to overwhelm you, both mentally and physically. All jokes about them not being able to hit a thing (yes yes, they don’t hit waddling 3PO and R2 in the hallway when they wander through that firefight…very amusing. But on the other side of them, a whole lot of Rebel troopers are shown getting dropped. The plain truth is…they weren’t AIMING for the droids.), it takes something to go marching into a combat zone in bright white armor. Stupidity, you may say, but I say thee nay! Discipline and fanaticism -two things you want to foment in a stormtrooper recruit.
It’s the same assurance that puts the TIE fighter pilots (the ONLY front liners who deserve to wear the black) into the cockpits of unshielded ships. Survivability is not a concern of stormtroopers. They’re a cog in a really big, really nasty machine and they know they can be replaced. That’s why the Emperor did away with all those pretty primary colored unit designations and emblems from the Clone Wars. The New Order isn’t about unit distinction, it’s about raw power.
Look at the Scout Troopers on Endor. No camouflage seems silly, right? When the Scouts hit the ground, the Empire is sending a message. That message is, we don’t give a laughin’ fuzzball about your planet. Not about your flora, not your fauna. We’ll stomp your trees with our AT-AT’s (rhymes with Rat-a-tat-tat-tat-a-tat-like that. And I never hesitate to put a Rebel on his back). Our Scouts don’t hide. They fly by on their speeder bikes and leave you smoking.
But what about Snowtroopers (my faves), you might say? They’re all white, they buy into the appeal of camo. Nope. Snowtroopers wear what Snowtroopers wear to keep warm. Hoth just happens to compliment Snowtroopers. It’s not the other way around. That’s why they run the joint. Snowtroopers weren’t made for Hoth. Hoth was made for Snowtroopers.

Only one pair of black boots on the ground.
So yeah, black-clad stormtroopers. They just go against the whole notion of crushing faceless uniformity I’ve come to love in the Empire. You wanna be a special snowflake, go be a Royal Guard. The job is cushier and you get a pointy movealong and a flashy red dress.
On top of all that….when I’m playing Battlefront I can never see the little buggers.

I see you in the back, you jerk!
May The Force Be Witcha.
