ISW: Russia creates formations engaged in urban combat

Russian commanders are reportedly constructing specialized company-size units within key frontline formations engaged in urban combat to reinforce the diminished combat effectiveness of most Russian units.

Caliber.Az reports citing the US think tank Institute for the Study of War (ISW) that a reliable Ukrainian reserve officer released a reportedly captured document on April 6 detailing the recruitment of personnel (who receive the status of BARS reservists) to form new “Storm Z” companies within elements of the 8th Combined Arms Army (Southern Military District) and the 1st Army Corps, the armed forces of the Donetsk People’s Republic.

Each “Storm Z” company is created outside of the conventional army unit structure and apparently is formed of newly recruited reservists and attached in some manner to existing Russian regiments and brigades, rather than adding additional assets or providing specialized training to existing frontline companies. It is unclear at this time how these “Storm Z” units fit into Russian command structures at the battalion level and above and why Russian units are forming new companies, continuing a standing Russian tendency throughout the war in Ukraine to break down doctrinal unit structures.

Each company is comprised of 100 personnel, broken into four capture squads (10 personnel each), four fire support squads (10 personnel each), a 2-person company command element, a 5-person combat engineering group, an 8-person reconnaissance group, a three-person medevac group, and a 2-person UAV crew.

Storm Z” companies are intended to conduct urban combat operations or operations in complicated geographic areas to capture important and strategic objects such as strongholds, command posts, and communication centers.

The Ukrainian reserve officer noted that the personnel that staff these companies receive 10 to 15 days of refresher training, a remarkably short amount of time to adequately train personnel (even reservists with some experience) to perform complex combat tasks and create unit cohesion.
