Hundreds of Illinois National Guard members are headed to Afghanistan, the largest such deployment in a decade.

About 400 members of the 1st Battalion, 178th Infantry Regiment of the National Guard, headquartered on Chicago's South Side, will begin a more than yearlong deployment in support of counter-terrorism efforts.

The soldiers will first spend a few weeks undergoing training in Fort Bliss, Texas, before heading to Afghanistan around Sept. 28.

The number of U.S. troops in Afghanistan has declined in the past decade, however there are about 14,000 U.S. service personnel still in the country.

Illinois Governor J.B. Pritzker was in attendance Sunday and in his speech said, "the fundamental strength of the National Guard is that it is a force of ordinary citizens committed to extraordinary work...and Illinois guard operates at highest levels of that commitment."
