I know i know before you tell me that it has been already posted,i'm not speaking about a voice command or a radial menu thingy.
I can ensure you that 50% of Squad's players including me (before a while ago ) are not aware that suppressing fire is very important and needed in combat.
Some people just tend to shoot unless they see an enemy peeking and hold fire until he comes out again of that corner. NO NO!
Suppressing is needed and those 5 or 6 mags (not really sure) were given for a reason which is KEEPING the enemy pinned down so your squad mates such as medics and AT's can do their job properly especially your squad leader.
So one simple suggestion which may have been suggested from a different point of view (but i did use the search bar moderators ):
You see that enemy markers thingy? Just switch that name to Markers instead or keep it like that afterwards:
Add a suppressing fire icon in between these 4 markers and that's it.You know that these markers can be put unless you are looking at that exact location so for example when my guys are panicking and need guidance i just look at a wall place a marker and ask them to suppress it,we will have enough time to get revived or retreat.
Your suggestions are needed buddies AND I REAAAAAALy need this as an active squad leader.
