IEDs were recently added to the game (Zues update), but only Zues can place them. Players can disarm them, but it comes up with an error saying that there is no object of a "disabled IED". The ability to place / pick up the IEDs would really improve gameplay and a lot of missions. In Arma 2 the IED was an object, why not Arma 3? An example of a cool scenario could be that Zues places down a civilian and an ammo box with an IED in it. Zues remotely controls the civilian, and takes the IED out of the box. Then he "unknowingly" walks onto a key road in full view of a military patrol nearby. They see him place an IED, and call in a DAGR strike with a laser designator. This would be so cool! Also it wouldn't look as weird as an IED disappearing into thin air.
