DeepState, a Ukrainian group of military analysts, has reported that the Russians have for the third time, following incidents near Sudzha and Avdiivka, used pipes to infiltrate their groups.

Quote:"The pipe entrances are located near Lyman Pershyi. Specially designed wheeled platforms are used for moving inside the pipe, along with electric scooters in areas with sufficient height. The route to the outskirts of Kupiansk takes about four days, so special resting places and food supplies have been set up.

In this way, enemy groups reach Radkivka without serious losses and from there move south into the forest, which they control. After that, they disperse in Kupiansk and reach the railway."

Аналітики проєкту DeepState повідомляють, що росіяни втретє після випадків біля Суджі та в Авдіївці використали труби для просочування своїх груп.

Details : Positions have been set up in Kupiansk itself for Russian FPV drone pilots to launch.

A problem is the lack of forced evacuation of local residents, who stay in the same houses as the Russians, making it impossible to strike.

Background:On the morning of 8 March, about 100 Russian soldiers used the gas pipeline to reach the positions of Ukraine’s defence forces near Sudzha.
