About 20 soldiers from the Arkansas Army National Guard`s Company D 114th Aviation have been called to active duty and will mobilize Sunday. The unit will report to Fort Stewart, Georgia, and will deploy to Kosovo in the Balkans region sometime next year. The unit will provide air traffic control for the Aviation Task Force in the region and any aircraft operating in the vicinity. Major General Don Morrow of the Arkansas National Guard says the skilled unit`s training program has been used as an example for other units around the country. Company D has been on two other operational deployments: Haiti in 1995 and Bosnia-Herzegovina in 2000.
