On the tenth anniversary of 9/11, just as he has done in years past, a  top military intelligence analyst identified by the US government only  as "Iron Man" will hunker down in front of his television and watch a  particularly gruesome scene of the carnage left behind on that fateful  day.
"Although I try to avoid it, I glimpse a film clip, a scene, of people  throwing themselves from a burning tower, people who deserved better  protection from their country, from me and the men I worked with, and I  hear the sounds of the lobby in the [World Trade Center] on tape," said  the man, whose alter ego chosen by the government appears to be paying  homage to the Marvel Comics 
superhero .  "To me, the sights and sounds, the smoke of that day are not yet  history. They are a knot, a silence, a facial tick, a missing friend in  Iraq. They are not history yet."
For many Americans, the emotional reaction to President Barack Obama's  announcement last month that a Navy Seal team had killed Osama bin Laden  during a raid at his compound in Pakistan was celebratory. But for  others, like the mysterious Iron Man, who has spent his career lurking  in the shadows, the death of the late al-Qaeda leader is a painful  reminder of what could have been avoided had the government heeded  numerous early warnings of an impending attack against the very targets  terrorists struck on 9/11.
The intelligence failures leading up to the attacks on the World Trade  Center and the Pentagon are an issue the media - and lawmakers - put to  bed years ago, despite the fact that new information continues to  trickle out, undercutting the integrity of the official investigations  into who knew what and when.
It was an 
exclusive story   Truthout published May 23 in the wake of Bin Laden's death, focusing on  a little-known intelligence unit that was ordered to stop tracking his  movements prior to 9/11, and led Iron Man to contact Truthout to 
share previously undisclosed documents he recently obtained under the Freedom of Information Act (FOIA) ,  which appear to cast further doubt on the official narrative and  suggests high-level military and intelligence officials withheld key  evidence from Congressional lawmakers probing the attacks.
The materials Iron Man provided to Truthout stand as the most revealing  information to surface in years regarding Bin Laden and al-Qaeda's  plans to attack the United States.
This is the first page of "Iron Man's" complaint to the  Department of Defense Office of Inspector General related to  intelligence work he did on Osama Bin Laden and al Qaeda. 
Formal Complaint
Five years ago, Iron Man, who requested Truthout conceal his true  identity out of concern for his family's privacy, lodged a formal  complaint with the Department of Defense's Office of Inspector General  after he was accused of improperly handling classified material.
Iron Man filed a FOIA request in September 2006, seeking a declassified  copy of the six-page complaint he filed with the inspector general's  office. He finally received a copy on April 8, just a few weeks prior to  the raid on Bin Laden's compound.
What he revealed in that letter, portions of which were redacted by the  government because the information is classified, is the inner workings  of an elite intelligence unit he headed at one point: the Asymmetric  Threats Division, formed in 1999, and "charged with reporting on  asymmetric threats, especially terrorism."
The unit worked with Joint Task Force-Civil Support (JTF-CS), also set  up in 1999. According to the Defense Department (DoD), JTF-CS was  charged with supporting "terrorist response operations in the  continental US" and providing "military assistance to civil  authorities."
The Asymmetric Threats Division is referred to as DO5, a branch of the  Joint Forces Intelligence Command (JFIC), whose responsibilities  included, among other things, vetting human intelligence sources on  behalf of the Defense Intelligence Agency (DIA). From 1998 to 2001, Iron  Man was working as a counterterrorism/counterintelligence analyst for  the Naval Criminal Investigative Service (NCIS), assigned to JFIC.
The JFIC is an elite intelligence unit that falls under the authority  of the United States Joint Forces Command (USJFCOM) and "had a direct  and assigned purview on international terrorism against the US, to  include the operations of al-Qa'ida and the 9/11 attackers."
The JFIC was also responsible for monitoring Bin Laden and other  suspected terrorists who resided in Afghanistan between 1998 and 2000  and was charged with constructing likely scenarios that could be carried  out by terrorists and possible government responses.
Iron Man noted the "purpose of the letter" he wrote "is to formally  complain" to the inspector general that "JFIC, when instructed in or  before May 2002 to provide all original material it might have relevant  to al-Qa'ida and the 9/11 attacks for a Congressional inquiry,  intentionally misinformed the Department of Defense that it had no  purview on such matters and no such material."
"JFIC's role" and the DoD's "role, in the pursuit of al-Qa'ida before  9/11 and timely analysis of the targets actually struck by the 9/11  attackers have remained unknown even to senior DoD officials," the  letter says.
Moreover, there has never been a public accounting of the work  conducted by DO5. But Iron Man's letter provides deep insight into the  secret military intelligence group's highly classified activities.
Tracking Terrorists
DO5 was "a fore-runner of current all-source fusion centers," the  letter Iron Man wrote says. Individuals assigned to the unit had "a wide  mix of skills" in intelligence disciplines, including human and  open-source intelligence, signals intelligence and imagery and signature  intelligence.
DO5 drafted "numerous original reports ... identifying probable and  possible movements and locations of Usama bin Ladin and Mullah Omar,"  including likely identification of the house where Khalid Sheikh  Mohammed allegedly planned the 9/11 attacks.
From 1999 to 2001, the intelligence unit also "conducted imagery  analysis of Jalalabad and Qandahar" and other parts of Afghanistan as  they were "pulled into a community-wide initiative on al-Qa'ida."
The letter further states, "DO5 was able to 'scoop' [the National  Geospatial Intelligence Agency]," an agency which played a crucial role  in identifying the compound in Pakistan where Bin Laden had been hiding.
According to US government officials, it was one of Bin Laden's most  trusted couriers, whom intelligence operatives identified about five  years ago, that led the CIA to pinpoint Bin Laden's Abbottabad compound.
But Iron Man's 2006 letter states that DO5 worked closely with DIA and  was instrumental in identifying "a likely financial courier" for  al-Qaeda, and one who may have led intelligence officials directly to  Bin Laden well before 9/11.
Early Intelligence Pointed to the World Trade Center, Pentagon
In 2002, following his departure to DIA, Iron Man returned to JFIC to  teach two classes on asymmetric warfare, and he kept "numerous" slides  related to DO5's work on "pre-9/11 briefings."
As Iron Man explained in his letter of complaint to DoD's inspector  general, "upon my arrival at DIA, I had these documents e-mailed from  JFIC to my DIA account, so that I could use them as references for the  asymmetric warfare course I was drafting for DIA, and as references for  any future counter-terrorism work I might pursue at DIA."
It appears that the allegation Iron Man mishandled classified material  stems from a decision he made to email the briefing slides to his DIA  account. Iron Man declined to elaborate about the circumstances of the  allegations leveled against him. Still, what he reveals in his carefully  worded letter in response to those charges is explosive.
"I kept the original classifications on the slides, as historical documents, although the fact that al-Qa'ida 
was likely to attack the World Trade Center and the Pentagon was clearly no longer classified." (Emphasis added.)
Iron Man further elaborated on this point by stating that high-level  DoD officials held discussions about DO5's intelligence activities  between the summer of 2000 and June 2001 revolving around al-Qaeda's  interest in striking the Pentagon, the World Trade Center (WTC), and  other targets.
In other words, the Bush administration was fully aware the terrorist  organization had set its sights on those structures prior to 9/11 and,  apparently, government officials failed to act on those warnings.
For example, Iron Man states in his letter that in the summer of 2000,  DO5 briefed USJFCOM senior intelligence officials and staffers,  including the deputy commander in chief, on the "WMD Threat to the U.S."
Iron Man describes a "sensitive," "oral briefing" that took place that  summer "indicating that the World Trade Centers #1 and #2 were the most  likely buildings to be attacked [by al-Qaeda], followed closely by the  Pentagon. The briefer indicated that the worst case scenario would be  one tower collapsed onto another."
Furthermore, as he states in his letter, Iron Man was certain that such  a scenario was part of a "red cell analysis" discussion that took place  prior to the intelligence briefing and included a finding that the  buildings "could be struck by a jetliner." He wrote that there was a  suggestion about alerting WTC security and engineering or architectural  staff, "but the idea was not further explored because of a command  climate discouraging contact with the civilian community."
One official who attended the DO5 briefing was Vice Adm. Martin J.  Meyer, the deputy commander in chief (DCINC), USJFCOM (Iron Man's  complaint does not identify Meyer by name, but notes the presence of the  "DCINC" for USJFCOM). But despite the red flags raised during the  briefing, 
Meyer   reportedly told Maj. Gen. Larry Arnold, the commander of the  Continental United States NORAD Region (CONR), and other high-level CONR  staffers two weeks before the 9/11 attacks that "their concern about  Osama bin Laden as a possible threat to America was unfounded and that,  to repeat, 'If everyone would just turn off CNN, there wouldn't be a  threat from Osama bin Laden.'"
Mayer retired from the Navy in 2003 and was 
hired  by defense contractor Lockheed Martin.
Intelligence Withheld From Congress
Even worse, according to Iron Man's letter, the information DO5 had  collected about Bin Laden, al-Qaeda and the lead up to 9/11 was withheld  from Congress after the House and Senate Intelligence Committees  launched an investigation into the attacks.
"When the Justice Department requested all documents relating to 9/11  from DoD in May 2002, I notified [redacted] in the DIA Congressional  Affairs office that I retained these documents," Iron Man's letter  states. "I spoke to [redacted] JFIC DI1 [an individual who works in the  command administrative staff], who informed me that JFIC had already  submitted a response without any documents. I was surprised and  disappointed when my successor at DO5 [redacted] notified me of the full  JFIC non-response. I notified [redacted] in the Congressional Affairs  office, and was told to submit the documents as DIA documents, with an  explanatory e-mail. I did so on 29 May 2002, presuming (probably  correctly) that the documents might be overlooked, since they originated  at JFIC. I forwarded copies to [redacted] (who was departing JFIC that  week), (his subordinate), and [redacted] (who was also departing JFIC  that week)."
A DoD spokesperson did not respond to requests for comment.  Spokespeople for the House and Senate Intelligence Committees also did  not respond to calls for comment.
After raising his concerns, Iron Man, who from late 2000 to June 2001  was acting head of DO5, was told by his former boss that JFIC's formal  response to Congress' inquiries was that "al-Qaida and the 9/11 attacks  had been outside JFIC's purview and that JFIC consequently held no  material on those issues," which was a lie.
Iron Man's boss said, "He insisted [to officials who responded to the  Congressional inquiries] that such was not the case, but was told this  was JFIC's response."
Iron Man wrote that "many people" working at government agencies were  knowledgeable about JFIC's "role in preparing original analysis" on  al-Qaeda, including officials at the CIA, NCIS, USJFCOM, DIA and NSA,  whose names were redacted in the letter he sent to DoD's inspector  general.
However, after conducting at least 300 interviews and reviewing  hundreds of thousands of pages of documents, the final report issued by  the House and Senate Intelligence Committees in December 2002, into  "Intelligence Community Activities Before And After The Terrorist  Attacks Of September 11, 2001" did not cite any of DO5's work on  al-Qaeda or Bin Laden or the fact that the intelligence unit was able to  identify the terrorist group's top two targets in the US. The later  2004 9/11 Commission Report did not mention DO5 or JFIC.
Flawed DoD Investigation
Although the inspector general acted on Iron Man's complaint and  launched an investigation, the findings of the probe, outlined in a 
report ,  declassified last year, previously reported by Truthout, was highly  flawed and failed to address Iron Man's charges that intelligence was  withheld from Congress.
Indeed, it appears the author of the inspector general's report  confused Congress' investigation into the 9/11 attacks with the  independent 
National Commission on Terrorist Attacks Upon the United States ,  otherwise known as the 9/11 Commission, created in late 2002 by  legislation passed by Congress. The inspector general's report insisted  it did not find any "evidence that the Joint Forces Intelligence Command  misled Congress by withholding operational information in response to  the 9/11 Commission."
But Iron Man's complaint specifically addressed intelligence withheld  from Congress' inquiries into the 9/11 attacks, not the independent  panel's probe, thereby dismissing an allegation Iron Man had never made.
Iron Man told Truthout the inspector general's final report "was, shall  we say, very incorrect, and intentionally did not address the full  scope of the [his] complaint. "
The watchdog did not tackle another of Iron Man's explosive claims  about DO5 briefings that centered on "numerous examples and suggestions  of how [Osama bin Laden] was being hunted by JFIC and could be hunted by  the [intelligence community]."
One such briefing held for a "DIA senior intelligence officer on  counterterrorism" was entitled "The Search (for Osama bin Laden) - A  [commander in chief] Level View," which included "a compendium of  imagery of [a] suspected [Bin Laden] house dating from 23 August 1999  until 11 April 2000."
At the briefing, intelligence officials were informed that "eleven  special reports" by DO5 had been disseminated in the "Daily Intelligence  Summary on [Bin Laden], Taliban leadership, Afghan military movements,  UN locations, and the economic status of Afghanistan."
Another briefing for the counterintelligence/counterterrorism chief at  NCIS, and about 30 NCIS agents, "clearly stated the JFIC's Asymmetric  Threat Division monitored 'worldwide  [counterterrorism/counterintelligence] traffic' and routinely prepared  'analytic reports' and 'supplements national agencies with original  intelligence on [Bin Laden] and Afghanistan.'"
Congress was kept in the dark about those discussions and was not shown  the documents distributed to intelligence officials at the briefings.  The inspector general never bothered to find out why. Remarkably, the  watchdog stated in its report, "JFIC did not have the mission to track  Usama Bin Ladin or predict imminent US targets."
Iron Man told Truthout it was key intelligence withheld from Congress  about al-Qaeda and Bin Laden's pre-9/11 activities that also played a  part in his decision to file a complaint with the inspector general.
"My concern was not only that the 9/11 commission had not been  informed, but the larger Congress, in its larger oversight  responsibilities, had also not been informed," he said.
A Heavy Burden
What remains unclear is exactly what took place back in May 2006 that  prompted Iron Man's complaint to the inspector general, given that the  issues he had raised centered on events that unfolded four years  earlier.
The answer to that question can be found in these passages of Iron Man's letter, particularly the last few sentences:
"My motivation for this complaint is multi-faceted," Iron Man wrote.  "I do believe that knowledge of the work done by DO5 would add to DoD's  understanding of its role in the events leading up to 9/11, and how to  avoid future attacks ... I have been falsely accused of revealing  classified information on DO5's work, when I am certain that information  is not and has not been classified since 9/11, and I do want to see  myself cleared of that false accusation.
"In addition, I and the deputy of that team, [redacted], especially  carried the burden of knowledge of how close DoD came to bin Ladin and  perhaps being able to reduce the number of lives lost on 9/11 ..."
The deputy whose name the government redacted from Iron Man's letter,  is believed to be Kirk von Ackermann, a former Air Force captain and  intelligence analyst, who was working for the US Army as a contractor in  Iraq and disappeared in October 2003 while traveling between Tikrit and  Kirkuk. A computer, a briefcase containing $40,000, and other materials  were found in von Ackerman's vehicle after he went missing.
Because von Ackerman's name was classified in the complaint Iron Man  filed with the inspector general, he could not confirm whether von  Ackerman is the individual he was referring to.
Just three months after Iron Man filed his complaint with DoD's  inspector general, in August 2006, the Army Criminal Investigative  Service concluded that von Ackerman had been kidnapped and killed. His  remains have never been found nor has anyone claimed responsibility for  his death.
Von Ackerman's 
tragic story   has been previously reported by journalist-blogger Susie Dow on the web  site e Pluribus Media, but has largely remained under the radar. In a  May 6 article she published on her personal blog, Dow identified von  Ackermann as a member of JFIC's Asymmetric Threats Division. Iron Man's  complaint suggests he ultimately became deputy chief of DO5.
In October 2006, Dow 
wrote  that von Ackermann was "assigned to a counterterrorism team."
"You'll find no mention of either Kirk von Ackermann or his team in the  9-11 Commission report.... Well before 9-11, Kirk von Ackermann  predicted aircraft could be hijacked and used as weapons against the  United States. He also predicted potential targets."
Von Ackerman's wife, Megan von Ackerman, has maintained a blog called "
Missing in Iraq ,"  dedicated to her missing husband. In March 2006, she wrote that her  husband had planned for such a catastrophic event, but his warnings were  ignored:
"... When 9/11 happened everyone around us reacted as normal,  civilians would - shock, horror, fear ... but Kirk, isolated from the  intelligence and military community of people who knew what he knew,  felt what he felt, was essentially alone," Megan von Ackerman wrote.  "For a year he had spent his days imagining just this sort of scenario.  He had come up with countless plans, evaluated targets, totaled up  casualties and estimated political value. He had thought like a  terrorist so he could stop them. Now he had to watch it made horribly  real - the nightmare he had worked so hard to avoid ... Kirk had tried  to make the warning, he had worked endless hours to stop this very thing  happening. He knew he had no guilt that he had been ignored. But he  retained an enormous sense of responsibility - not only for what  happened, but for dealing with the new world that 9/11 ushered in."
Knowing exactly how close he, von Ackerman and DO5 came to capturing  Bin Laden and possibly thwarting the attacks on 9/11 is a "burden" Iron  Man said he "no longer wants to carry."
"[Redacted] and I discussed this issue the last time we spoke," Iron  Man wrote in the final paragraph of his letter to the inspector general,  likely referring to von Ackerman. "He remains the longest missing man  in Iraq in this war, and I want, one day, to be able to explain to his  children what their father foresaw."
