The black-and-white aerial footage shows a line of purported Taliban insurgents slowly walking along a path in a lightly forested desert in Afghanistan's western Farah province. Suddenly, the screen flashes to white as the men disappear in a fireball — the result of a bomb dropped from a U.S. MQ-9 "Reaper" drone.
"Taliban fighters on the run following Afghan-led offensive in #Farah province, #Afghanistan. Video shows U.S. airpower (MQ-9s) in support," declared a short message accompanying the video, which was posted on the official account of the U.S. military in Afghanistan. Subsequent footage showed more Taliban scrambling, in an unsuccessful attempt to avoid the airstrikes.
The Pentagon footage was released Wednesday, as U.S., NATO and Afghan government forces were locked in a fierce battle with the Taliban for control of the capital of Farah, which borders Iran.
The tweet was unusually graphic. While the U.S. military often releases footage of buildings or vehicles being destroyed, it does not as frequently distribute videos that show individuals being bombed.
Less than 24 hours later, the U.S. Air Force posted its own Afghanistan-related tweet that raised eyebrows — this one referencing a viral audio clip that has sparked a lighthearted online debate among those who hear the word "Laurel" and others who hear "Yanny."
"The Taliban Forces in Farah city #Afghanistan would much rather have heard #Yanny or #Laurel than the deafening #BRRRT they got courtesy of our #A10," read the Air Force tweet.
The Air Force has since apologized and deleted the tweet, saying it was sent in "poor taste." The USFOR-A tweet remains.
In a statement to VOA, a Pentagon spokesperson said the tweets do not represent a new social media strategy.
"As with any other organization, the post was an attempt to bring awareness to a major/ongoing organizational activity by tying it to references or conversations already trending with their established audiences," said Lieutenant Colonel Kone Faulkner.
