So here is an idea.
Separating a nine man squad into fire teams or patrols by color, such as in arma 2`s ace mod.
This would make leading a squad much simpler. Also setting a fireteam/patrol leader would make issuing orders much simpler. Squad members would identify patrol leaders with a corporals rank next to their name much like the squad leaders, which is a sergeant.
For example a nine man squad separated in to three man patrols (taken from a FDF manual)
Squad leader - Medic - Support rifleman.
Patrol leader - Machine gunner - Rifleman
Patrol leader - Machine gunner- Engineer
Not sure if this is all ready planned or in game yet but nevertheless I would like this to be added.
