One of the Hoosier troops is Maj. Curtis Madsen, Brazil.
"I'm excited to get to work with soldiers from other countries," Madsen said. "It'll be a fabulous and unique experience."
Before the Hoosier troops stamp their passports for the overseas mission, they'll first head to Fort Polk, La., for theater-specific training. Once the training is complete, they will then pair up with their Slovak counterparts.
This multinational cooperation is stemmed from the National Guard's State Partnership Program that started in 1993 to help Eastern European and western Asian countries gain acceptance into NATO after the fall of the Soviet Union.
Now the two countries' troops will mentor and advise members of the Afghan army as part of the NATO-led Operation Mentor and Liaison Team program, which is scheduled for a six-month deployment in Afghanistan.
