Washington, D.C. — (RT) US Central Command has been misleading the public in its assessment of the overall progress in the war on terror by failing to account for thousands of airstrikes in Afghanistan, Iraq, and Syria, a Military Times investigation reveals.

The investigation revealed that open source data of US Air Force strikes does not contain all the missiles fired. That incomplete data, however, continues to be used by the Pentagon on multiple occasions in official reports and media publications.

The publication says that in 2016 alone, American aircraft conducted at least 456 airstrikes in Afghanistan that were not recorded in the database maintained by the US Air Force.

SPECIAL REPORT: The US military’s stats on deadly airstrikes are wrong. Thousands go unreported https://t.co/hprq3nanbF w/ @SnowSox184pic.twitter.com/hHfpaskAgJ — Andrew deGrandpre (@adegrandpre) February 5, 2017

The investigation also revealed discrepancies in Iraq and Syria where the Pentagon failed to account for nearly 6,000 strikes dating back to 2014, when the US-led coalition has launched its first airstrikes against Islamic State (IS, formerly ISIS,ISIL) terrorist targets.

According to the Air Force, coalition jets conducted 23,740 airstrikes through the end of 2016. The US Defense Department, however, puts the number at 17,861 until the end of January 2017.

“The Pentagon routinely cites these figures when updating the media on its operations against the Islamic State and al-Qaida affiliates in Iraq and Syria,” the publication says.

Military Times remains especially puzzled by a statement made by an Air Force official in December who assured the publication that its monthly summary of activity in Iraq and Syria “specifically” represents the entire American-led coalition “as a whole, which is all 20-nations and the US branches.”

“It’s unclear whether this statement was intentionally misleading, or simply indicative of widespread internal ignorance, confusion or indifference about what’s contained in this data,” Andrew deGrandpre, Military Times’ senior editor and Pentagon bureau chief, said in the article.

Military Times says that the “most alarming” aspects of the investigation are that the discrepancies in numbers go back as far as 2001, when the US, under George W. Bush’s administration, struck Afghanistan in response to the 9/11 attacks on American soil.

The publication reveals that the unaccounted-for airstrikes in all three war zones were allegedly conducted by US helicopters and armed drones which are overseen by US Central Command.

“The enormous data gap raises serious doubts about transparency in reported progress against the Islamic State, al-Qaida, and the Taliban, and calls into question the accuracy of other Defense Department disclosures documenting everything from costs to casualty counts,” deGrandpre wrote.

The Pentagon and Army did not immediately respond to requests for comment.

“Those other key metrics include American combat casualties, taxpayer expense and the military’s overall progress in degrading enemy capabilities,” the publication added, wondering whether the military wanted to mislead the American public.
