Sojka III is an unmanned aerial vehicle (UAV) operated by the Czech Army until it was decommissioned in December 2011.

The mission of Sojka ("jaybird") is to provide aerial reconnaissance, radio reconnaissance, artillery fire observation, electronic warfare, or to launch infrared targets for air defence training.

A Sojka unit usually consists of three or four Sojka UAVs, a transport truck, launch truck, control and monitoring vehicle, and an off-road vehicle for transport of the landed UAV.

The Sojka is launched from a ramp using a rocket-assisted device to get takeoff speed.

A wind speed of lower than 8 km/h is required to get a good optical environment.
