Over the 12 months preceding September 11, the Army’s DiLorenzo Tricare Health Clinic (DTHC) at the Pentagon works to develop its mass casualty (MASCAL) plan. This work will significantly and fortuitously help the clinic when it has to implement the plan in response to the Pentagon attack on 9/11. Major Lorie Brown, the chief nurse at the DTHC, is the chairperson for the DiLorenzo Action Response Team (DART). As she will later recall, over this 12-month period, the DART team works “on developing that [MASCAL] plan, really creating a whole new plan. We sat down and met on numerous occasions with the Air Force clinic [also based in the Pentagon], civilian EMS [Emergency Medical Services], Pentagon and [Department of Defense] hierarchy, DPS [the Defense Protective Service], and with the other civilian medical agencies.” They work through various issues, such as “what would happen in the event of a MASCAL, what each of our roles would be.” The DART team, Brown says, participates “in several large tabletop exercises with these external bodies, to include FEMA [the Federal Emergency Management Agency] and the others I just mentioned. We even did our own internal exercise where we made up the scenario of a plane crashing into the building.” [Office of Medical History, 9/2004, pp. 7] This “internal exercise” is likely a reference to an exercise held by the DTHC in May 2001 (see May 2001). [US Department of Health and Human Services, 7/2002, pp. B17] Another exercise Brown participates in over this period is the Pentagon Mass Casualty Exercise in October 2000 (see October 24-26, 2000), which also includes a scenario of a plane hitting the Pentagon. [MDW News Service, 11/3/2000] Brown will later credit this work developing the MASCAL plan as being of great benefit when the Pentagon is hit on 9/11, and the plan is initiated (see Soon after 9:37 a.m. September 11, 2001). She will say: “[O]ur planning truly made such a huge difference on that day. Our commander had the foresight to focus on MASCAL prep and gave us the time and budget to really revamp our old MASCAL plan. I can’t say enough about how critical this was to our success.” [Office of Medical History, 9/2004, pp. 7]

Peter Chiarelli.Peter Chiarelli. [Source: US Army]Army officers plan an exercise for the Army’s Crisis Action Team (CAT) at the Pentagon based around the scenario of a plane crashing into the World Trade Center, which they intend to run during the week following September 11. The officer who is in charge of preparing the exercise is Major General Peter Chiarelli. Chiarelli took over as the Army’s director of operations, readiness, and mobilization around early to mid-August this year. In this position, he is in charge of current operations in the Army Operations Center (AOC)—the Army’s “command and control center,” according to Chiarelli—located in the basement of the Pentagon. [US Army Center of Military History, 2/5/2002; Soldiers, 9/2004; Army News Service, 8/5/2008]
New Army Director Plans to Run Crisis Team Exercise - Chiarelli will later recall how the plans for the exercise come about. He will tell an interviewer that in some of the briefings he received when learning about his new post, he was told “that the Crisis Action Team had not stood up, except for an exercise, in about 10 years in any great role.” Therefore, after beginning in the post, he “planned to do an exercise for the Crisis Action Team.” Around the same time, the Personnel Contingency Cell, which is one of the CAT’s support teams, has been directed to put together a new mass casualty standard operating procedure (SOP) for the Army.
New Operating Procedure Has Scenario of Plane Hitting WTC - About a week before 9/11, Raymond Robinson Jr., the chief of operations for the Army’s deputy chief of staff for personnel, and two other officers come to brief Chiarelli on their new SOP. Chiarelli will recall, “The real amazing thing of that SOP is that the scenario was an aircraft crashing into the World Trade Center.” Chiarelli tells the officers, “Hey, not only is this a good SOP and a good plan, but at the same time, to really make this good, what we need to do is exercise it.” Therefore, as he will later recall, “[W]e decided to integrate a scenario like that into my first CAT exercise.” The scenario of a plane crashing into the WTC would be used “to drive this exercise” that Chiarelli is planning to run. Chiarelli will not say what type of aircraft is envisaged hitting the WTC in the scenario, nor specify whether it would have been a hijacked plane or one that crashed into the WTC accidentally.
Exercise Scheduled for September 17 or September 13 - The exact date on which the CAT exercise is set to take place is unclear. Chiarelli will say he has his “folks design it for me on the 17th of September.” [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 95-97] However, Army Center of Military History historian Stephen Lofgren will mention, while interviewing Chiarelli’s deputy, Brigadier General Clyde Vaughn, that the exercise is scheduled to take place “a couple of days” after September 11, meaning September 13. [US Army Center of Military History, 2/12/2002] The exercise is presumably canceled as a result of the 9/11 attacks. The CAT, whose members are set to participate in it, will be activated on September 11 in response to the attacks on the WTC, so as to “respond to the contingency in New York if requested by state and local officials.” [Goldberg et al., 2007, pp. 134]
