Why the Original Version Was Unreliable

The original article described a "72-hour rout" of two regiments near Terny, cited unsourced radio intercepts, and provided precise casualty percentages. Open-source reports do not confirm a short episode of such magnitude, the quoted statement, or the figures. In reality, battles in this sector continued for many months, and the composition of attacking units changed.

A reliable reconstruction is only possible at the level of confirmed deployments, directions of advance, and front-line changes. It shows the role of the 3rd Motor Rifle Division but does not allow for calculating its losses by individual regiments.

Geography: The Terny — Yampolivka — Torske Line

Terny is located west of Kreminna, along the Zherebets River line. Control over the area impacts approaches to Lyman and the roads connecting Ukrainian positions near Torske, Nevske, and Yampolivka. Forest belts, ravines, small watercourses, and a limited number of roads narrow the directions of armored vehicle movement.

Such terrain favors observation, mining, and strikes against convoys, but it does not, by itself, prove the existence of a pre-designed "fire sack." To establish a specific scheme, geolocations of each attack, positions of fire assets, and timing data are required.

Not a Single Rout, But a Year of Positional Battles

In January 2024, ISW recorded Russian advances east of Terny. The January 25 report, citing a Ukrainian military observer, mentioned units of the 252nd Motor Rifle and 237th Tank Regiments of the 3rd Division, which left equipment behind after an unsuccessful attack in the Yampolivka — Terny — Nevske direction.

On February 15, ISW reported that assault detachments of the 752nd and 252nd Motor Rifle Regiments of the 3rd Division participated in attacks in the Terny direction. This is direct confirmation of both regiments' presence in the campaign, but not proof of their simultaneous destruction.

By April, reports from Terny more frequently featured units of the 144th Motor Rifle Division, including the 488th Regiment. Ukrainian overviews also named the 254th and 283rd Regiments of this division. Therefore, attributing the entire cycle of attacks solely to the 3rd Division is incorrect: the 20th Army deployed several formations in the sector.

Why Attacks Might Continue After Losses

RUSI described Russian practice in 2024 as a series of smaller tactical attacks that maintain pressure and inflict losses on the enemy even without a major operational breakthrough. This model better explains the prolonged nature of the battles near Terny than a narrative of a single three-day catastrophe.

Chatham House noted that the structure of Russian units below regimental level had changed, and new battalions and reinforcements did not always correspond to pre-war establishments. Therefore, expressions like "regiment destroyed" or "completely reformed" require caution: the same designation can persist after significant losses and personnel replacement.

What is Known About the 252nd and 752nd Regiments

The 252nd Motor Rifle Regiment (military unit 91711) and the 752nd Motor Rifle Regiment (military unit 34670) are part of the 3rd Motor Rifle Division of the 20th Combined Arms Army. Open-source reports confirm their deployment in the northeastern sector of Donetsk Oblast and the adjacent part of Luhansk Oblast.

However, a 2022 source regarding 95% losses for one battalion of the 752nd Regiment pertained to a different phase of the war and was based on a statement by Ukrainian StratCom. It cannot be applied to the battles for Terny in 2024. Similarly, the capture of individual servicemen does not provide the strength of the regiment or its overall losses.

The assertion about a "Black Mamba" detachment, allegedly formed from prisoners and refuseniks within the 252nd Regiment, was not confirmed in the original set of sources. Without a primary document or several independent testimonies, it is excluded.

January 2025: Claim of Terny's Occupation

On January 14, 2025, the Russian Ministry of Defense claimed the occupation of Terny and attributed participation to units of the 144th Motor Rifle Division. ISW on that day found no independent confirmation of full control over the village. Ukrainian reports continued to mention battles near Terny.

Even if subsequent Russian control is considered established, the chronology shows the duration of the operation: approximately one year passed from the early 2024 attacks to the claimed result. This contradicts the headline about a 72-hour rout and emphasizes the positional nature of the campaign.

Losses and Missing in Action: What Cannot Be Stated

Open sources confirm equipment losses in individual attacks and the presence of killed, wounded, and captured servicemen. However, they do not provide a verifiable table of losses for the 252nd and 752nd Regiments specifically at Terny.

The original source also cited an anonymous appeal from a mother and claimed that the command intentionally uses the status of missing in action to freeze payments. Without a reference to the appeal, a court case, or an official departmental response, such a story cannot be published as a documented fact.

Conclusion

The 3rd Motor Rifle Division participated in battles in the Terny direction, as confirmed by reports regarding the 252nd and 752nd Regiments in early 2024. However, it was only part of a larger grouping of the 20th Army, and sources also linked the 144th Division to a key role in subsequent stages.

The history of Terny is not a proven "rout of two regiments in 72 hours," but a protracted campaign with local advances, unsuccessful attacks, rotations, and changes in the units involved. This formulation is what withstands verification by open-source data.
