Remove
 

i wanted to remove some stuff like the compass or health bar or the bullet bars on the sides or all of these, cause no soldier would really have these

Soldiers had Compasses...Granted, not magic compasses that pointed towards Berlin and Tokyo biggrin: , but Compasses nonetheless.

I don't recall hearing about any mods, but you might try getting in contact with someone like Fubah or NOTF Glory...they seem pretty good with HUD's and the like cool:

your right they do have compasses but i still dont like it being there. i wish you could press i button and it would turn it on and off.

use this: bind x "toggle ui_compass"

yes there r mods to get rid of it all..no hud mod

if you want to remove it all just type ui_hud 0 in console

unfortunately you cannot toggle the hud with 1 key. you have to use 2 keys, 1 for on and 1 for off. the compass alone is toggleable though.
