ESTIMATE OF CASUALTIES RESULTING FROM COALITION Filename:015me.91d DATE: 09 JAN 1991 TO: DISTRIBUTION LIST FROM: IRAQ INTERAGENCY BIOLOGICAL WARFARE WORKING GROUP, FUSION COMMITTEE SUBJ: ESTIMATE OF CASUALTIES RESULTING FROM COALITION AIR STRIKES ON IRAQI BW RELATED FACILITIES 1. Ongoing analysis of this issue leads us to believe that the original estimates of potential Iraqi casualties resulting from U.S. and coalition air strikes on BW related facilities was far too high. Further, we now believe that contrary to these original estimates, that there is little liklihood that there would be any threat to coalition forces as a result of these strikes. 2. One of the areas of greatest concern in attacking Iraqi BW facilities has been the amount of collateral damage that could be inflicted on the Iraqi' population, and potentially coalition forces, as a result of inadvertent aerosolization of Biological spores and toxins: It is believed that based on a thorough review of the information and exploitation of expertise available the original estimates, those appearing in the IIBWWG final report, are far to high and are the result of the very, even overly, conservative methodology applied. The original estimate assumed a total Iraqi anthrax inventory of about 3000 kgs. After a review of the available information, and the methodology used to derive that figure, it is believed that the estimate was three times too high, [ (b)(1) sec 1.3(a)(4) ] would indicate the actual size of agent inventory. Additionally, the methodology assumed virtually all of the Iraqi stockpile to be located at any one facility at any given time (a highly unlikely scenario), thus the absolute worst case situation is derived, in terms of collateral casualties, for the area surrounding that facility. Finally, two alternate cases were developed where it was assumed, lacking better data at the time, that either 1O% or 1% of the agent present would be aerosolized. Such factors as wind direction, inversion conditions, spore degradation due to environmental factors, etc., were then cranked into the model and the resultant high and low casualty figures were derived for each BW facility. Here unfortunately, more as a result of presentation than anything else people seeing the data assumed that the figures for each location were cumulative and interpreted them accordingly. Unfortunately what in fact happened as a result of the method of presentation is that the entire Iraqi inventory is placed in each facility, casualty figures are derived for each, but then added up cumulatively. The resultant figure is representative of the entire Iraqi Anthrax inventory x the number of facilities used, a far from accurate picture. 3. To further complicate the issue it turns out that the figures used for aerosolization of agent that would result from a coalition-strike, 1 to 10 %, is much to high based on experience with the U.S. BW program in the 196Os. In consultation with individuals with considerable experience in this area it was determined that the actual amount of anthrax spore that would likely be released, and then aerosolized, as a result of an attack by high explosive munitions using an optimized attack profile would be no greater than 0.001 - 0.1, (10 grams - 1 kg), and probably less. 4. The attached chart shows a comparison of the newly derived figures which represents the official position of the IIBWWG with the previous worst case model. Note that the figures are not cumulative, but are stand alone for each facility noted. The holders of the IBBWWG final report should add this chart to the Collateral Risk Assessment section of that report and either remove the existing charts or accurately reflect that the collateral casualty estimates are not valid [ (b)(2) ] CA, Senior Intelligence Officer: Chairman IIBWWG Fusion Group DIST: HOLDERS OF IIBWWG FINAL REPORT DIA- DR DD ED CA VP JS/J2 [ (b)(2) ] [ (b)(2) ] AFXX AFMIC Facility Estimated Casualties* Worst case** Probable case*** Bunkers/No. Salman Pak (2) 39-61,000 Hundreds Al Fallujah (2) 24-56,000 Hundreds Ash Shuaybah (1) 10-17,000 Hundreds Ad Diwaniyah (3) 5-17,000 Hundreds- thousands Kirkuk (1) 4-10,000- Hundreds An Nasiriyah (4) 2-3,000 Hundreds- thousands Karbala (2) 1-6,500 Hundreds Qabatiyann (1) 500-2,500 Hundreds Tikrit 500-3,000 Tens-hundreds Habbaniyah (1) DNA DNA Production Taji 120-224-, 000 Less than 5,000 *Assumes uniform population distribution outside of Baghdad. **A night time attack with high explosive weapons resulting in heavy damage/total destruction with the release of 10-100 kg anthrax spores.
