Name and scope of the article

The first Karenni concurrent operation that was announced were Operation 1107, with fighting reported in places like Mese outside Loikaw. Shortly afterwards, in November 2023, Operation 1111 was announced for Loikaw.
By February–March most sources were already using Operation 1111, though the Washington Post used "The battle for Loikaw" for operation 1111 and "October offensive" for Operation 1027.
As of June–July 2024 most sources seem to have defaulted to using exclusively Operation 1111 for all Kayah/Karenni State related fighting. Pro-Tatmadaw sources use generic terms to describe the karenni fighters as "terrorists".
By August 2024, even some pro-Tatmadaw sources had started employing the term Operation 1111, though in combination with the generic label terrorist.
The term has been used as of November 2024, despite changes on the battlefields since the launch of Operation 1111. The term still seeing usage as of March 2025.
June 2025, Operation 1111 is mentioned in past-tense, in reference to first phase of this article.
Term seeing use as of September 2025. As of October 2025, the term is used in past-tense, this time alluding up to and including the intensification phase, past the first phase, by counting "Although they failed to capture Loikaw, they seized several towns" indicating the later phase when several towns were captured.
What is also noteworthy is the sources keep using Operation 1111 for the fighting in Kayah since November 2023, when earlier there were articles for separate battles of Loikaw for the separate bouts of fighting, like Battle of Loikaw and Battle of Loikaw.
In May 2024 the Tatmadaw begun and still by August 2025 Tatmadaw were launching its own Operation Yan Naing Min named Operation partially overlapping with Operation 1111.

Background

Loikaw has been described as the military's nerve center for Kayah State. Its loss could jeopardize the regime's control of much of the state. It has been the site of multiple battles during the civil war: the first battle in 2021 that ended in a ceasefire, and another battle in January–February 2022 that ended inconclusively.
Before the start of the 2023 battle, the junta had two battalions deployed to defend the city.

Starting at 4:00am on 11 November, KNDF and KA forces started attacking military bases around Loikaw in an operation dubbed "Operation 1111". The coalition forces captured seven military bases and shot down an aircraft.
By 13 November, the Karenni Nationalities Defence Force claimed it had taken several positions of the Tatmadaw. It was also reported that a total of 16 civilians had died in the fighting. The Irrawaddy reported that "volunteers estimate that around 35,000 people—including people displaced by previous conflicts—need to evacuate from Loikaw as a result of the recent fighting. The town is usually home to 50,000 residents. The capital is also the junta's key stronghold and center of administrative control in Kayah State."
By 15 November, there were reports of heavy fighting in Loikaw, with many civilians still trapped in their homes amid the ongoing fighting. More than 34 civilians were killed, and 50 were injured in Loikaw from retaliatory strikes from the junta's forces. During the fighting, 110 junta soldiers were killed and 38 surrendered.

The fighting had reached the downtown of Loikaw by 23 November. In an interview with The Irrawaddy on 28 November, the KNDF's deputy commander-in-chief Marwi claimed that the rebels already controlled 80% of Kayah state and had surrounded Loikaw, where an interim Karenni government was being established. With its ground forces in Kayah State weakened, on 29 November, the junta began to resort to airstrikes against Loikaw. In a report to the State Administration Council, Chairman Min Aung Hlaing claimed that the Tatmadaw had retaken the city, but these claims were denied the following day by Marwi.
Reports emerging in August 2025 stating Demoso town was captured by the Karenni by November 2023.

Markets, farming, and small businesses were opening in area's on the outskirts. During this time the KNDF was consolidating control over much of Kayah since the Tatmadaw were sending reinforcements to Loikaw from elsewhere in Kayah. At this time, the Karenni resistance were still urging civilians not to return to Loikaw during the fighting.
The Irrawaddy reported in July 2024, that the offensive to take Loikaw had seen little progress since the Karenni took the Loikaw University.

Escalation

In March 2024, Al Jazeera reported a counter estimate on how much of Loikaw the Karenni forces actually control, stating "About half the city, controlled by the military since the coup, is now in the hands of the Karenni resistance".
