US Army soldiers were demoted to a lower rank after they broke coronavirus lockdown in South Korea to go to a bar.
The three military officers sneaked out of Camp Humphreys near Anjeong-ri and headed to a nearby watering hole.
They then returned to the base through a hole in the fence.
Movement has been tightly controlled in South Korea, which has made a huge effort to keep its coronavirus deaths low.
After they were caught the soldiers were demoted one rank and were docked $1,732 (£1,402) of pay, The Independent reported.
A statement from the 19th Expeditionary Sustainment Command read: "Doing the wrong thing has serious consequences.

"Don't risk everyone's safety and our ability to complete our mission because you can't follow orders."
The punishments were announced on social media "to ensure our soldiers, civilians, contract employees and their families understand the ramifications of not following the commander's directives" during the pandemic.
US bases in South Korea are being tightly monitored during the coronavirus lockdown, despite the fact only two service members on the Korean peninsula having fallen ill with Covid-19.
South Korea has taken its response to the coronavirus incredibly seriously from the early days of the pandemic.
It was announced today that officials are to strap electronic wristbands on people who ignore home-quarantine orders in the country's latest use of tracking technology to control its outbreak.
Vice health minister Kim Gang-lip said those who refuse to wear the bands after breaking quarantine will be sent to shelters where they will be asked to pay for accommodation.
Officials said around 46,300 people are under self-quarantine.
The number ballooned after the government began enforcing 14-day quarantines on all passengers arriving from abroad on April 1 amid worsening outbreaks in Europe and the United States.
Although quarantined individuals have been required to download a tracking app that alerts authorities if they leave their homes, some of them have been caught slipping out by leaving their phones behind.
The wristbands will communicate with the phone apps through Bluetooth and alert authorities when people leave home or attempt to remove the bands.
South Korea has confirmed 10,708 cases since the onset of the outbreak and has reported several days of single-digit growth in its death toll.
Roughly 240 people have died of Covid-19 in the country.
