A new quarterly report by Washington’s Special Inspector General for Afghanistan Reconstruction (SIGAR) has documented a staggering 82 percent increase in insider attacks on Afghan government security forces in the first quarter of this year, resulting in 115 personnel killed and 39 wounded.

SIGAR reported this week that the overall Afghan National Defense and Security Forces (ANDSF) casualties were also substantially higher than during the same period last year.

SIGAR is not allowed to include full ANDSF casualty data because U.S. forces in Afghanistan keep it classified at the request of the Afghan government.

The report stated that the ANDSF suffered a total of 31 insider attacks between January 1 and April 1, and the number of casualties they caused were more than double compared to the same period in 2020.

SIGAR’s report comes as the US and NATO forces started to withdraw from Afghanistan as decided by US President Joe Biden last month.

In addition to the estimated 2,500 U.S. troops and the 7,000 NATO and allied forces, over 12,500 US Defense Department contractors will also withdraw. The are U.S citizens and third-country nationals.

SIGAR stated it is unclear who, if anyone, will replace contractor personnel or perform their work after their withdrawal.

“Without continued contractor support, none of the Afghan Air Force’s (AFF) airframes can be sustained as combat effective for more than a few months, depending on the stock of equipment parts in-country, the maintenance capability on each airframe, and when contractor support is withdrawn,” SIGAR said, citing U.S. military assessments.

According to SIGAR, DOD contractors provide for and maintain ANDSF ground vehicles and train local technicians. Although the ANDSF has “dramatically improved its share of the work, it is still falling well below benchmarks for its share of the maintenance work orders they — rather than contractors — are supposed to perform,” SIGAR reported.

Special Inspector General John F Sopko meanwhile stated that under the new posture that will follow the troops' withdrawal, SIGAR and its oversight mission will “assume even more important for the United States”.

He said as the largest oversight presence in Afghanistan and the only one with statutory whole-of-government authority, SIGAR will be the only government agency capable of overseeing the billions of U.S. taxpayer dollars already appropriated that will continue to flow into the country despite the absence of U.S. military - including U.S. defense contractor - boots on the ground.

Sopko said SIGAR is well-prepared for this enhanced role and stands ready to assume any new responsibilities assigned to it by Congress and the Administration.

He pointed out that while the Biden Administration conducted its review of U.S. policy in Afghanistan, the Office of Management and Budget requested the data that underpins the reporting in SIGAR’s quarterly reports concerning U.S. funds appropriated for Afghanistan since 2002.

“This recognition of the quarterly report’s function as the most authoritative source for information about U.S. spending in Afghanistan came as the report continues to expand its coverage of U.S. appropriations,” he said.

He also stated that U.S. officials have indicated that they intend to condition U.S. assistance to Afghanistan on the actions of the Afghan government and possibly the Taliban.

“As U.S. policy on Afghanistan continues to evolve, my colleagues and I will work with Congress, the Administration, and other stakeholders to guard against the waste, fraud,
and abuse of U.S. funds devoted to that country’s reconstruction,” he said.
