Rtut-BM / 1L262E

A Russian mobile electronic-warfare system intended to protect troops from munitions fitted with radio proximity fuzes.

Overview

Rtut-BM is a tracked Russian electronic-warfare station built around a specific defensive task: interfering with radio proximity fuzes on incoming artillery rounds and rockets. The manufacturer, Rostec's KRET group, says the system senses a fuze's frequency and transmits a signal intended to make the munition burst before it reaches the protected area. Rostec's account describes a protected area of up to 50 hectares. That figure is a company claim, not an independently measured combat result.

The system matters because proximity-fuzed ammunition is designed to burst above exposed personnel and equipment. An effective countermeasure would reduce that effect, but the published record establishes the system's presence more firmly than its battlefield performance. A 2015 Ukrainian delegation document presented at the OSCE identified a 1L262E in northern Luhansk. That is a Ukrainian identification in an OSCE-hosted record, not a finding by OSCE monitors.
