Change behaviour in "Awear" mode so the AI prefer to crouch when not moving and prefer stand when moving.
There are 4 modes; Stealth, Danger, Awear and Relax.
All different scale of exposure.

I really can't see the difference between Relax and Awear.
So in Stealth and Danger the AI in your team can't keep the pace.
In Awear mode when you stop scouting, they stand like Scarecrows in a field.

From real life operations, every soldier during mission where there is enemy present, they crouch or prone while securing their sector.
