On 24 March 1999, the North Atlantic Treaty Organisation (NATO) launched Operation Allied Force against Serbia.
Lasting 78 days, this was an unusual conflict fought at several levels. The campaign was fought at the negotiation tables, in the media, and via cyber warfare. In the air, NATO sought to destroy or at least minimise the capability of the Serbian forces, while on the ground the Serbian forces fought the Kosovo-Albanian insurgency. It had an unusual outcome, too: without NATO losing a single soldier in direct action, they still forced the Serbian authorities and armed forces to withdraw from Kosovo, which in 2008 then proclaimed its independence. In turn, the war inflicted serious human and material losses upon the Serbian's and the air force was particularly devastated by air strikes on its facilities. Nevertheless, many within NATO subsequently concluded that the skies over Serbia were as dangerous on the last night of this conflict as they were on its first.
