THE Southern African Development Community Task Force is poised to establish a command structure to effectively rebuff a rebel onslaught in the east of the Democratic Republic of the Congo. “We felt that such a unified command structure will co-ordinate our forces and strategically combat fierce fighting in the east of the country,” Brigadier-General Denga Ndaitwah, deputy commander of the task force said on Friday. Separate command structures are not working effectively enough, he said.
