Any deployed weapons under the new fatigue rules suffers from unreasonably high sway values conceptually associated with the soldiers heavy breathing after strain.
while this is sensible as a factor affecting shoulder firing stances (upright or crouched) - it is not realistic and very frustrating to experience how this also effects firing from a stabilized position with the gun rested on a solid object and/or elbows to the ground (i.e. when prone)
one of the main reasons a shooter seeks shooting from a deployed position, even without a bipod, is that the object being rested upon supports most of the mass of the weapon - thereby removing almost, if not all, unwanted motions inherent of the human body as a firing platform.
critically in fatigue conditions, the use of a deployed firing position over hand-held shooting should enable near-perfect accuracy for short and medium range targets
