OBS:
All units simultaneously report "Ready" at the very start of the opening cinematics of each mission in the official East Wind campaign. The effect is almost comical and breaks immersion.
It is most apparent in hub missions due to the large number of units near the player's starting position.
Presumably this issue affects other missions.

EXP:
No units should be heard during the opening cinematics, as was the case with previous Arma builds.
