To keep ammunition and ammunition safe from drone attacks, artillery fire and grenades.

Three versatile building segments form a tube enclosed on one side by a lid, open on the other side for quick access and handling. Without gunports and portholes. The 30 tonne capacity construction provides additional restraining mass. In the event of an explosion of the stored material, it directs the pressure wave outwards from the tube, reducing the risk of concrete parts flying around. A protective berm constructed around the sandbag bunker will limit the velocity of projectiles, secondary shrapnel and shock pressure waves. Internal volume 28m3. Advantage of quick assembly of the modular system.
