The possibility of constructing charged particles in gauge theories has long been the subject of debate. In the context of QED we have shown how to construct operators which have a particle description. These operators have a gauge invariant decomposition which plays a key role in the infrared dynamics of charges. We have also shown in QCD how antiscreening is generated by one of these factors. In this paper we extend this program by showing how the screening interactions arise through the effects of the other part of the charge.
