Russia is making the use of its glide bombs a priority, and it's causing devastation on the front lines

• Russia is intensifying glide bomb attacks on Ukrainian defenses. 
• It is adapting old Soviet bombs into powerful new weapons.
• Russia is making their use a "priority", a Ukrainian official said. 

Russia is stepping up the production of a powerful long-range bomb which it's using to devastate Ukrainian defenses, reports said.

The "glide bombs" are old Soviet-era weapons that are fitted with guidance systems and wings, enabling them to be launched at a long distance by Russian fighter planes to strike Ukrainian positions.

They include the FAB-250, FAB-500, and FAB-1500, which are named after their respective weights in kilograms.
