1 | Operation Allied Force: âThe Most Precise Application of Air Power in Historyâ William M. Arkin |
At two in the afternoon Washington time, 8:00 P.M. local time on March 24, 1999, the North Atlantic Treaty Organization (NATO) initiated offensive military operations against Yugoslavia. Thirteen (of 19) NATO members committed aircraft, and eight put their planes in action to bomb a sovereign nation that had attacked neither any alliance members nor its neighbors.1
Operation Allied Force came after more than a yearâs effort by the six-nation Contact Group (including Russia) to find a negotiated solution to stop Serbian human-rights violations in Kosovo, one of four jurisdictions of the Federal Republic of Yugoslavia (FRY).2 In 1998, systematic violence against ethnic Kosovar Albanians erupted, and by the fall an estimated 250,000 Albanians had been driven from their homes by Yugoslav military and paramilitary forces. Intelligence agencies predicted that tens of thousands were threatened by approaching winter weather. The situation prompted the United Nations Security Council to adopt resolution 1199 (UNSCR 1199) on September 23, calling for a cease-fire and the return home of refugees and the internally displaced.3
Throughout the crisis, NATO had prepared and refined military options to amplify the diplomatic process. âActivation warningsâ for two different air operations were issued the day after the Security Council passed UNSCR 1199. One operation was known as the Flexible Anvil âLimited Air Responseâ and the other as the Allied Force âPhased Air Campaign.â4 Flexible Anvil, relying predominantly on cruise missiles, âwas designed as a quick-strike, limited-duration operation, primarily to be used in response to a specific event.â5
Richard Holbrooke, the Clinton administrationâs chief Balkan troubleshooter, departed for Belgrade on October 5 to meet with Yugoslav President Slobodan Milosevic. To demonstrate allied resolve, NATO on October 13 issued a higher activation âorder,â threatening air action. In the face of this threat, Milosevic seemingly gave way. He agreed to reduce Serbian security forces in Kosovo and to permit international verification missions in and over the province. The North Atlantic Council (NAC) agreed to a âpauseâ in its threats, and in late October it suspended execution permission for air operations.6
After a brief period when conditions in Kosovo seemingly stabilized, attacks against ethnic Albanians resumed. On January 15, 1999, a massacre of 45 civilians allegedly occurred in the village of Racak. The Contact Group called on both sides to end the cycle of violence, summoning representatives of the Belgrade government and Kosovar Albanians to Rambouillet, France, for direct discussions on how to end the violence in Kosovo. On January 30, the NAC authorized NATO Secretary General Javier Solana to commence air strikes against Yugoslav targets if an agreement was not reached.
But the Rambouillet talks ended unsuccessfully on March 19, and NATO began preparations to initiate bombing. Days before the talks broke down, Belgrade launched âOperation Horseshoe,â its methodical campaign of ethnic cleansingâYugoslav troops and 300 tanks were massing in and around Kosovo.7 Holbrooke once again flew to Belgrade on March 22 in a last-ditch effort to bring Milosevic to terms. That same day, the NAC authorized Solana, subject to further consultations, to ready a broader range of air options.8 NATO planned initially to conduct a two-day demonstration strike hitting targets throughout Yugoslavia âin an attempt to convince Milosevic to withdraw his forces and cease hostilities.â Two escalating response options would back up the 48-hour plan: the first, a response to continued Yugoslav acts in Kosovo, and the second, a response to aggression against NATO.9
Many in the NATO leadership and member governments remained hopeful that a show of force would compel Milosevic to yield. âThere was that abiding belief⌠that the campaign will last two nights and that after two nights, Mr. Milosevic would be compelled to come to the table,â said one senior U.S. general.10 After the fact, U.S. officials claimed that they had cautioned allied leaders not to initiate strikes unless they were willing to escalate and go all the way. But there is no evidence that the principal playersâSolana, Holbrooke, and General Wesley Clark, the Supreme Allied Commander Europe (SACEUR), in particularâquestioned expectations that limited strikes would succeed in coercing Milosevic.11
This chapter describes the 78-day air war that ensuedâfrom its diffident beginning on March 24 until its abrupt conclusion on June 10. The focus is on the military dimensions of Operation Allied Force: the conduct and the evolution of the bombing campaign that became in the eyes of its proponents âthe most precise application of air power in history.â
The Plan
Every military operation begins with a plan, and Operation Allied Force began life as NATO OPLAN 10601. The official history says that preparation of 10601 began in response to a NATO directive in June 1998. In reality General Wesley Clark, who was both SACEUR and commander in chief (CINC) of United States European Command, directed General John Jumper, commanding U.S. Air Forces in Europe, to begin developing options for an air war a month before, in May. In other words, U.S. planning for what would become Operation Allied Force began prior to and proceeded separately from the planning effort within NATO. This penchant for âU.S. onlyâ planning reflected Washingtonâs greater propensity to use force, an assertion of American prerogatives as the dominant partner in the North Atlantic community, and the complicated relationship of Clark, as the theater CINC, with his air-warfare subordinates. As part of the American effort to portray the U.S. role as âsupporting [and] not leadingâ the NATO effort, attempts were made to portray the separate track as existing only to the very limited extent that operational security demanded it.12 But even as the conflict began, separate NATO and âU.S. onlyâ tracks continued, with alliance members denied the details of U.S. cruise-missile strikes and operations by B-2 and F-117 stealth aircraft.
Between the summer of 1998 and March 1999, NATO and U.S. planners examined an assortment of alternatives, from the limited air response to a robust âU.S. onlyâ option called Nimble Lion, and even to âforced entryâ ground campaigns. Planners found themselves responding to General Clarkâs ever changing âcommanderâs intent,â which provided guidance on what targets would or would not be hit in Yugoslavia. First Clark asked for a plan that would focus on five key radio-relay nodes, then for an unlimited campaign, then for strikes limited to below the 44 degree north longitude, then for a campaign employing cruise missiles only, then for one executed exclusively by U.S. and British forces. Throughout, however, certain key requirements remained fixed: Minimize collateral damage, avoid any friendly losses, and preserve the Yugoslav civil infrastructure.13
According to General Clark, shifting military priorities reflected an absence of political consensus. âThere simply was no consensus on the part of the nations to lay in place the full array of military options,â he would later testify.14 In some ways, then, from the very beginning the prospect of escalation was implicit in any âplan.â Alliance members who were determined to use force were willing to sacrifice military realism to secure political unity, believing that, once military action had begun, NATO would have no choice but to expand operations as conditions required. Should a mere show of force be unsuccessful, doubting parties would be lobbied to agree to do more.
By the time Allied Force commenced, NATO had gone through more than 40 iterations of the air-campaign plan. The version actually initiated on March 24 included three combat phases. Phase 1 would establish air superiority over Kosovo and degrade command and control throughout Yugoslavia. Phase 2 would attack military targets in Kosovo and those Yugoslav forces providing reinforcement into Kosovo south of 44 degrees north latitude. Phase 3 would expand air operations against a wide range of military and security-force targets throughout Yugoslavia, including the capital city Belgrade. If Phase 1 did not force the Serbian leadership to accede, Phase 2 and 3 would up the ante.15
Within each phase, significant disagreements existed inside both the U.S. and NATO militaries with regard to strategy and priorities. Those engaged in Nimble Lion planning wrestled with a host of constraints: targets within Montenegro were restricted, and critical command and control nodesâparticularly telephone exchangesâremained off limits due to concerns about collateral damage, as did electrical-power generating plants and television transmitters. One effect of the restrictions was to preclude a concentrated effort in the initial 48 hours to neutralize Yugoslav air defenses. The ostensible priority at the outset of hostilities would be to establish air supremacy, but the constraints actually worked against that goal.
Looking beyond the 48-hour bombing âdemonstration,â General Clark and his air-warfare commander, U.S. Air Force Lieutenant General Michael Short, disagreed fundamentally about the proper design of an extended campaign. Should it concentrate on âstrategicâ targets in Yugoslavia or on âtacticalâ targets throughout Kosovo? Short believed that âBody bags coming home from Kosovo didnât bother Milosevic, and it didnât bother the leadership elite.â16 Taking Desert Stormâs 1991 strikes on Iraq as his model, he argued for delivering a powerful strategic blow against the Serb leadership in Belgrade. âI believe[d] the way to stop ethnic cleansing was to go at the leadership⌠and put a dagger in that heart as rapidly and as decisively as possible,â he told Congress after the war.17
Clark, applying what Vice Admiral Daniel J. Murphy, commander of NATO naval forces, called âa ground commanderâs perspective,â had other ideas.18 He wanted Yugoslav forces to bear the brunt of NATOâs attacks. His focus was not only the perpetrators of ethnic cleansing on the ground in Kosovo, but also special police and paramilitary forces throughout Yugoslavia.
Among army officers, a belief that wars are ultimately decided on the ground is an article of faith. But if Clark was affected by service bias, other matters also weighed heavily on his thinking. He, and not General Short, was directly responsible for translating political guidance into operational plans. He, not his air commander, appreciated how fragile and tentative was the consensus within the alliance in support of any military action. If commanders became too insistent in demanding a more aggressive approach to using force, they would undermine that consensus andâwithout a shot having been firedâhand Slobodan Milosevic a victory.
Thus, from his vantage point in Belgium, Clark concluded that his political masters would never agree to opening the war with a Desert Stormâstyle all-out air assault on Belgrade. Advocating only the most modest bombing campaign enabled Clark to reassure those alliance members hoping that Milosevic might yet have a rapid change of mind. Doing so also seemed to signal that NATOâs military chiefs saw no need even to consider mounting a ground invasion, a prospect that several members of the alliance were unwilling to countenance even as a theoretical possibility.
In short, NATO began the war without having achieved any consensus on what the alliance would do if the hostilities extended beyond 48 hours. Although the very fact that it was a âphasedâ campaign implied the possibility of escalation, the alliance had postponed any decision on what that escalation would entail. Clark and his civilian masters would play it by ear: if Milosevic did not quickly cave in during Phase 1, there would be opportunity to escalate and accommodate alternative approaches.
In practice, this was an invitat...
