425th Assault Regiment (Ukraine)
Ukrainian military intelligence unit
The 425th Separate Assault Regiment "Skelya" (formerly "Skala") (Ukrainian: 425-й окремий десантно-штурмовий полк «Скеля»; MUN A4862) is a unit of the Ukrainian Ground Forces formed by Yurii Harkavyi "Skala", whose nickname "Skala" ("Rock") gave the unit its name. It has taken part in operations in the Russian invasion of Ukraine starting in 2022, such as assaults on enemy positions and using aerial drones to hunt Russian soldiers, having success in the 2022 Kharkiv counteroffensive working with the 93rd Mechanized Brigade.
Skala has been described as a specialized unit that has demonstrated high efficiency on the battlefield in conducting aerial reconnaissance and assault operations, employing drones, tube artillery and rocket artillery, and tanks. The regiment has also been criticized for high level of casualties and accused of physical abuse and human rights violations against its servicemen.
History
The Skala Battalion was formed in 2022 by Yurii Harkavyi "Skala" initially as a military intelligence volunteer unit, later being reformed into an assault battalion.
The Skala Battalion took part in the defense of Bakhmut, being in the immediate vicinity when a Russian Sukhoi Su-24 was shot down.
During the 2023 Ukrainian counteroffensive, the battalion was deployed on the southern front in the Zaporizhzhia direction, participating in the Ukrainian advance into Robotyne.
In January 2025, the battalion was reinforced with tanks and artillery and then converted into a regiment. Despite this designation, the unit's size is closer to that of a division, numbering around 13,000 personnel as of 2026. On 20 May 2025, the regiment formed the first motorcycle assault company in the Ukrainian military, presumably based on similar companies used by the Russian Armed Forces.
This brief starts where responsible research should: with the source description of “425th Assault Regiment (Ukraine)” as ukrainian military intelligence unit. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as ukrainian military intelligence unit. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q116447755. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022, 2023, 2025 and 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
