(I translate)
There is also the arrival of U.S. troops in Uganda, officially to hunt the LRA of Joseph Kony. Why these 100 U.S. military personnel have to be deployed in Uganda now, not after the elections in the DRC? These U.S. Marines came with sophisticated equipment that was not even waited by Ugandan officials. According to information relayed in The Monitor, the Ugandan army spokesman acknowledged that his army was surprised by the arrival of U.S. military hardware. Some sources claim that three Drones are also expected in the next few days in Kampala. These unmanned aircraft, which can be remotely from California, scare several senior African policy makers who fear their use for purposes other than tracking down the LRA of Joseph Kony.

What bothers African “policies makers” is not so much LRA than what US intend to do with 100 guys in Kampala.
But I personnaly think it's a good thing to have 100 US SOF ready to be deployed in Uganda. Just in case of... things turn ugly in Kinshasa.
