The South African National Defence Force is comprised of the South African army, navy and air force, as well as a military health service. According to Global Firepower the country's arsenal includes 250 tanks, 240 rocket projectors, 235 aircraft and three submarines. While South Africa has one of the smaller armies on this list in terms of personnel, they are considered the most advanced military in terms of technology. Before the end of Apartheid South Africa had developed nuclear weapons, and despite destroying them, there is still a weapons development industry in SA. The country is now starting to take a more active role in international peacekeeping efforts on the continent, but the recent tragedy in Central African Republic has shone a spotlight on the weaknesses of the the SA armed forces.
