The Rwanda Defence Force (RDF) is the national army of Rwanda. Largely composed of former Rwandan Patriotic Army (RPA) soldiers, it includes the Rwanda Land Force, Rwanda Air Force and specialised units. After the successful conquest of the country in 1994 in the aftermath of the Rwandan genocide, the Rwandan Patriotic Front decided to split the RPF into a political division (which retained the RPF name) and the RDF, a military division which was to serve as the official army of the Rwandan state. Defence spending continues to represent an important share of the national budget, largely due to continuing security problems along the frontiers with the Democratic Republic of the Congo and Burundi and lingering concerns about Uganda's intentions towards its former ally.
