How do you tell each other apart?

[Mortogg]

Height and body sizes are sometimes the easiest to tell but when you all look the same a fine eye can pick up miner details in some peoples body language or posture. How they stand or present themselves, head movement or how they hold their weapons and stand at ease, this can change with some troopers who often will wear not only their armour but a character aswell so you tend to know who the clown or the tuff guy/girl is with a quick glance. And then you got minor armour differences like scuff marks around the legs or other armour parts where things have been cut and molded different.

I can pick most troopers out in a crowd but gets tricky with more newer troopers as they often change their character from troop to troop till the find a comfortable feel for themselves.

Just takes a lot of training of the mind to spot those small differences that any other person would never see.
