About 580 soldiers in a Stow-based Ohio National Guard unit are deploying to the Middle East this weekend.

Ohio Governor Mike DeWine and Major General John C. Harris Jr., Ohio’s adjutant general, will send off the unit during a call to duty ceremony at 1 p.m. Sunday at the Canton Memorial Civic Center, 1101 Market Ave. N. The public is invited.

During the deployment, which is in support of Operation Spartan Shield, the soldiers of the 1st Battalion, 145th Armored Regiment will be part of the 30th Armored Brigade Combat Team, which is made up of 4,200 National Guard members from Ohio, West Virginia, North Carolina and South Carolina.

The 30th Armored Brigade Combat Team will replace the 3rd Armored Brigade Combat Team, 4th Infantry Division, as part of a regular rotation of forces in support of Operation Spartan Shield.

In 2009, about 450 members of the 1-145th Armored Regiment returned from a yearlong deployment in support of an international peacekeeping mission in Egypt’s Sinai Peninsula.
