Rostec showed a mobile version of the Citadel 30mm anti-aircraft artillery system. Now the combat module, the radar and the optical detection systems are located on a vehicle chassis. Judging by the published images, the Tornado-U armored vehicle is used as a base. The main advantage is portability. The compound can be quickly moved between objects, improving their protection against air threats. In addition, the mobile version expands the capabilities of fire teams to locate and activate aerial targets. Now air defense mobility is a necessity. The faster the team can change position and cover the desired area, the more difficult it is for the enemy to implement his plans using a UAV.
