Ukraine’s anti-FPV road net tunnels
Ukraine has published a manual of standardized, detailed instructions for building anti-FPV road net tunnels.
Two main designs are covered, one for up to 20km from the front where the risk of FPV attacks on the construction unit is acute, and another for greater than 20km.
