Hi
How do you know if for example a if a enemy has a legendary or eilte ect on the field
Will it say eilte transport
I would like to know

The only way of knowing somewhat which rank a unit is, is to look at it's physical appearance, and look for any upgrades that are only for specific ranks.

in short: no

The russian transports get radar dishes when they reach lengendary. Its basically a way of saying "Hey!!! Im a lengendary unit, unit kill me!!!!"

dude, they get that when they hit veteran, i have a dish on 3 out of 4 transports, guess you'll have to kill em all to find out which two are legendary, if i don't kill yours first

My SGB Elite artillery have 3 barrels but you will never see them I dont use them!!!

I always though it would be cool to customize your legendary units

Imagine your legendary tanks with like Flags or banners on it, looking all tight with blood tallie marks marking how they kills they have

but then that just screams "EMP+WMD Here"

lol so true

Tanks are the most easily destingushed units since all 3 factions have specific unit upgrades for any thing higher than Harden
Transports as well, if you have good eyes so is Infantry, Artillery is only JSF & EFEC since SGB don't have any physical upgrades, besides defense upgrade 1, choppers you need goods eyes, EXTREME HAWK EYES for CV
