If you’re an infantryman stationed in South Korea, say hello to an earlier curfew.

Soldiers with the 2nd Infantry Division will have to be inside an hour earlier after the division released a memo on Tuesday, according to Stars and Stripes.

Troops with 2nd ID are now required to be on base, at a residence or inside a hotel room by midnight instead of 1 a.m., the memo said.

The curfew, or “readiness call,” still ends at 5 a.m.

“The recall readiness time was moved one hour earlier in order to ensure that the division is consistently and completely in compliance with the U.S. Forces-Korea readiness recall policy,” division spokeswoman Lt. Col. Junel Jeffrey told Stars and Stripes.

Neither 2nd ID nor South Korean police reported an increase of incidents involving U.S. troops, but the unit said readiness of its 12,000 troops was the main concern, the newspaper reported.

The unit’s readiness recall policy requires 90 percent of 2nd ID soldiers to assemble within four hours.

The memo also throws a potential wrench in the Memorial Day weekend plans for soldiers who are deployed to South Korea, Stars and Stripes reported.

Along with the curfew, the memo said non-emergency leave and off-peninsula passes won’t be issued for rotational units, such as the 3rd Infantry Division’s 1st Armored Brigade Combat Team out of Fort Stewart, Georgia.

“Given [Tuesday’s] effective date of the policy, fewer than 15 rotational training unit soldiers may be affected, and the command is working with those soldiers on a case-by-case basis,” Jeffrey told the newspaper.
