CAMP DOUGLAS, Wis. -

About 100 members of the Wisconsin Air National Guard's 128th Air Control Squadron returns to Wisconsin Friday evening after a six-month deployment.

Gov. Scott Walker, Maj. Gen. Donald Dunbar and senior Wisconsin National Guard officials are expected to join family and friends when the soldiers return to Volk Field at Camp Douglas.

The 128th Air Control Squadron was sent to the Middle East to support the 727th Expeditionary Air Control Squadron's mission of providing air surveillance, threat warning, theater command and control and communications. During the deployment, the 128th tracked more than 241,000 aircraft and supported more than 150 exercises.

The unit also deployed in 2003, 2006 and 2009.

Aircraft maintenance issues delayed the soldiers’ return for two days.
