A modular mobile shooting station having a HVAC system, and air filtration unit, and a dust control device for use in hot desert and cold areas. A dust control device has an open and a closed position. When it is in the closed position, it forms a compartment around a weapon. The compartment forms a trap to preventing the discharged dust (muzzle blast) from escaping towards a shooter behind a shield, and instead directs the dust out through a shooting opening. The shield is part of the dust control device. The dust control device can be utilized in a mobile station or a stationary firing ground. 1110100110.
